Description Nathan Toone 2005-02-12 22:19:02 UTC

Version:           3.3.92 (using KDE 3.3.92 (beta2), Gentoo)
Compiler:          gcc version 3.4.3 20050110 (Gentoo Linux 3.4.3.20050110, ssp-3.4.3.20050110-0, pie-8.7.7)
OS:                Linux (i686) release 2.6.10-gentoo-r7

Some animated gifs (from www.w3schools.com and rollingstone.com that I know of...) crash all of KDE.  They don't take up CPU resources like other bug reports have shown.  I have isolated one which causes it, and will upload it as an attachment.

Comment 1 Nathan Toone 2005-02-12 22:20:11 UTC

I'm marking this a "grave" because it's very important not to crash an entire system when diplaying a web page...

Crashes KDE

When using latest for CVS-HEAD (but has been happening for a couple of months -
took me a while to isolate), this image will crash all of KDE, and X-windows. 
The only solution is a hard reboot.

This image is from http://www.w3schools.com - there are other "evil" animated
gifs around - but they are kind of hard to isolate...

This image will not crash opera or firefox, and since it is not animated in
kuickshow or kview, it doesn't crash when loaded in those programs as well. 
When loaded in konqueror (either embedded within a web page, or loaded directly
from the file browser), it crashes.

Previous to crashing, the CPU is normal - it doesn't appear to be CPU-related.

Comment 3 Nathan Toone 2005-02-12 22:24:07 UTC

Warning - opening this file in konqueror *will* lock your computer... :)

Comment 4 David Vogt 2005-02-13 15:44:58 UTC

I can't reproduce this with KDE 3.4_beta1. The image displays nicely here. But something else happens - Konqueror's "world icon" doesn't stop turning, indicating that it's still loading.

Comment 5 Peter Thomassen 2005-03-02 23:10:07 UTC

I cannot confirm this, too.

But yes, the world icon turns on, see #4. Does this always occur with animated GIFs?

Comment 6 Nathan Toone 2005-03-02 23:17:52 UTC

Still existing in head...

Comment 7 Philippe Rigault 2005-03-07 17:07:11 UTC

Works fine here (KDE 3.4-rc1 compiled from sources, x86_64)
  - image displays nicely
  - konqueror's world icon is OK too (i,e it does not turn)

Comment 8 Nathan Toone 2005-04-20 12:06:36 UTC

This is most likely related to the NVIDIA drivers - see a discussion at http://www.nvnews.net/vbulletin/showthread.php?t=47502.  I have disabled "RenderAccel" as suggested in this thread, and have not had any problems since.
