263828 - Binary downloads not working (ignored)

Status: RESOLVED DUPLICATE of bug 227439

(SeaMonkey :: General, defect)

Description

[Tomas Hajny]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8a4) Gecko/20040927
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8a4) Gecko/20040927

I'm not able to download any binary file any more after installing 1.8a4.
Whatever I open directly in the browser window works (HTML, plain text), but
clicking on any link to binary files (should it be via HTTP, FTP or even stored
on local drive and accessed via file://) is either ignored, or an error message
about missing temporary file is shown for files with known application handlers
(like opening .doc file - Word is started as usually, but complains about not
having found the file in my temporary directory). The file is just not created
at all. If I ask for Saving the link target explicitely, I'm asked for the path,
but that's it again - no file is created there. If I configure Mozilla to open
Download Manager for downloads, it doesn't get open at all.

Reproducible: Always
Steps to Reproduce:
1. Open any page with links to binary files (e.g. Mozilla releases)
2. Right-click on one of links and select "Save target"
3. Choose path to save the file to.

Actual Results:  
Nothing - no file is created, no progress window or Download Manager window opened.

Expected Results:  
Download the file.

I didn't change my configuration too much after having installed the new version
(everything worked correctly for 1.7.1 installed before), just enabled the new
feature of automatic logon to proxy server and local intranet (shared sign-on
for Windows). However, the problem appears even if working with local (file://)
content not going through proxy, so it doesn't seem to be related to that
feature. In addition, I currently have installed the following add-ons:

- Checky
- Launcher
- ImageZoom
- Calender

Can you try deleting your compreg.dat in your components folder and see if that
makes downloads working again? You might also try going to the URL about:plugins
and then try to download again.

Yes, deleting the file helped. Sorry to bug you with this, I was really lost.
Does deleting this file have any side-effects? If not, wouldn't it be better to
have it deleted automatically during installation (I used the installer version)?

Thanks for your assistance.

Tomas

Well, this error shouldn't happen at all and it also happens when not upgrading
sometimes :/
