273617 - gnome mime-types are ignored in mozilla with gnome 2.8

Status: RESOLVED INVALID

(SeaMonkey :: General, defect)

Description

[Bob B.]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20041206
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20041206

Mozilla 1.7.3 on gnome 2.6 behaved well - if you have no helper apps defined, it
looked to "OS" level helper apps (in this case gnome).  This allowed us to set
gnome mime/types and helper apps in one place globally.

Upgraded to gnome 2.8, and now mozilla doesn't "recognize" gnome mime-types. 
Its falling back to /etc/mailcap...

I know there were significant changes in gnome-vfs in 2.8 for mime handling - so
I'm thinking this may be a backwards compatibility problem.  If this is a gnome
bug - my apologies.

I noticed the gnomevfs extension in the mozilla source tree - so I thought I'd
post here first.

Reproducible: Always
Steps to Reproduce:
1. install mozilla 1.7.3 under gnome 2.6
2. establish gnome mime-types and see how mozilla follows suit
3. upgrade to gnome 2.8
4. establish "freedesktop.org"-like mime types for gnome 2.8


Actual Results:  
mozilla no longer uses those gnome mime-types

Expected Results:  
should use gnome mime-types

Marco, any idea what's up here?

To the reporter, can you give some more details please?

Linux distribution
gnome-vfs version
shared-mime-info version

Please describe exactly the step to reproduce. Ex. configure the mime handler
for pdf in the nautilus file manager to be "Pdf Viewer", click on a pdf file in
mozilla, results etc...

Here it seem to work correctly...

Sorry for not being more verbose.

> Linux distribution

Gentoo 2004.0 - kernel 2.4.25

gnome-vfs-2.8.1-r2

> shared-mime-info version

shared-mime-info-0.14

NOTE:  I'm in a multi-user environment - 25 users running off of one machine -
so I need global mime-handler settings.

With Gnome 2.6, as root, I could run "nautilus preferences-all-users:///", go to
"File & Types", and establish global mime-handlers, which mozilla recognized
immediately.

With Gnome 2.8, there is no "File & Types" preferences dialog for establishing
global mime types/apps.  [NOTE:Mozilla stopped recognizing mime-handlers
immediately after upgrading to Gnome 2.8 - I rebuilt mozilla but still nothing.]
 Configuring the nautilus file manager with a mime-handler is a per-user
configuration - not acceptable - so I had to add things manually in /usr/share.
 Gnome seems to have abandoned /usr/share/mime-info (all my entries from gnome
2.6 are still there and nautilus/gnome/mozilla doesn't recognize any of them),
so I had to create a desktop entry in /usr/share/applications:

eg. acroread.desktop

[Desktop Entry]
Encoding=UTF-8
Name=Acrobat Reader
Comment=View PDF files
Exec=acroread %F
Icon=gnome-pdf
Terminal=false
Type=Application
Categories=Application;Viewer;
StartupNotify=true
MimeType=application/pdf;

and then run update-desktop-database and update-mime-database.  At this point,
for all users, nautilus could open files with "acroread".

But at this point mozilla still didn't pickup gnome mime-handlers (to test
properly, you need to be sure that ~/.mime.types, ~/.mailcap, /etc/mime.types
and /etc/mailcap do NOT exist - as these will override the gnome-vfs settings)

I had to add entries to /etc/mime.types and /etc/mailcap to get mozilla to work
properly:

eg:  in /etc/mime.types

application/pdf                 pdf

eg: in /etc/mailcap

application/pdf;acroread %s

Hope this clarifies the issue somewhat...

Do you have any other application supporting pdf mime type? What does mozilla
show as handler? Another app? Nothing?

Comment 5

[Bob B.]

Yes gpdf (gnome pdf) handles pdf types by default in gnome (I didn't
disable/remove this).

When I remove /etc/mailcap and /etc/mime.types (force gnome-vfs), I get the
following:

---
The file "blahblah.pdf" is of type application/pdf, and Mozilla does not know
how to handle this file type.  This file is located at...

What should Mozilla do with this file?

( ) Open it with "(blank)" [Choose...]
(.) Save it to disk
---

Note:  Behaviour is same for all other mime-types as well.

Hmmm weird, I dont seem to be able to reproduce this here. I have gnome-vfs
2.8.2 and shared-mime-info 0.15 though, maybe you could try to upgrade?
Also please check that nsGNOMERegistry.c is actually built in your mozilla tree,
gnome_vfs_application_get_default should really work, as it work in nautilus.

[Bob B.]

Upgraded to gnome-vfs-2.8.3-r1, restarted mozilla, and bingo - works!

Must have been a bug in 2.8.1??

Thanks Marco.

Comment 8

[Marco Pesenti Gritti]

Yeah, looks like that.

Closing as invalid because it's not a mozilla bug.
