212252 - dragging a selection causes reproducible lockup

Status: RESOLVED EXPIRED

(Core :: DOM: Selection, defect)

Description

[Peter Eckersley]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030704 Debian/1.4-1
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030704 Debian/1.4-1

I have had this problem periodically from at least 1.2 through to 1.4:

When I select a piece of text, and then drag it, I occasionally see the cursor
change to an "inverted L" shape, locking X in the process. Switching to a
console and killing mozilla-bin is the only way to recover.  This is observable
with debian and with mozilla.org binaries, and does not seem to be a duplicate
of the "popup dialogues during selection cause crashes" bug.

Reproducible: Always

Steps to Reproduce:
1.Select a few words/lines of text
2."drag" the text randomly with the left mouse button
3.repeat til lockup - this sometimes takes a minute or two

Actual Results:  
The cursor becomes stuck in "inverted L" drag and drop form, and X locks up. 
Recovery is only possible by killing mozilla-bin from the console

Expected Results:  
Not locked up :)

try:
1. waiting a really long time
2. hitting "Esc"

Comment 2

[Peter Eckersley]

I tried that (waiting a few minutes, pressing escape) -- no luck

Comment 3

I also just observed this behvaiour in Firebird 0.6 (using debian's 0.6-8 packages).

I'm not sure how to tag this bug as existing in Firebird, without moving it to
firebird...

most of the relevant code is shared, so that's to be expected.

Comment 5

[Christopher Blizzard (:blizzard)]

Two questions:

1. Is this a gtk 1.2 build or a gtk2 build?

2. Do you see it in the 1.4 final build?

Comment 6

[Peter Eckersley]

I'm currently seeing the bug with GTK2 builds (Debian's mozilla-browser 2:1.4-2,
library versions shown below); I'm pretty sure the upstream version I reproduced
it in was 1.4 final.  

I've also seen it in older GTK1.2 builds (such as 1.2.1-9, which it's reported
against in Debian's bug tracking system).

Versions of the packages mozilla-browser depends on:
ii  debconf        1.2.27         Debian configuration management system
ii  libatk1.0-0    1.2.4-1        The ATK accessibility toolkit
ii  libc6          2.3.1-16       GNU C Library: Shared libraries and Timezone
ii  libgcc1        3.3.1-0pre0    GCC support library
ii  libglib2.0-0   2.2.2-1        The GLib library of C routines
ii  libgtk2.0-0    2.2.1-2        The GTK+ graphical user interface library
ii  libnspr4       1.4-2          Netscape Portable Runtime Library
ii  libpango1.0-0  1.2.1-1        Layout and rendering of internationalized te
ii  libstdc++5     3.3.1-0pre0    The GNU Standard C++ Library v3
ii  psmisc         20.2-2.1       Utilities that use the proc filesystem
ii  xlibs          4.2.1-5        X Window System client libraries
ii  zlib1g         1.1.4-1        compression library - runtime

I haven't been able to reproduce this bug in mozilla for a while, which is a bit
odd.

But I did just see it in gaim, which presumably confirms that it's somewhere in
gtk (or another library).

For cross-referential purposes:
Versions of the packages gaim (1:0.67-3) depends on:
ii  libao2         0.8.3-1        Cross Platform Audio Output Library

ii  libatk1.0-0    1.2.4-1        The ATK accessibility toolkit
ii  libaudiofile0  0.2.3-4        The Audiofile Library

I can't reproduce with debian's:
mozilla-browser_1.7.3-5
libgtk2.0-0_2.4.14-2

Please confirm this bug or close it.

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
