Bug Description

Binary package hint: konqueror

Appears in Kubuntu Dapper RC (6.06 LTS)

When I'm browsing directory with video files in konqueror sometimes it crashes when I'm moving mouse cursor over video files to see a big preview of video clip in tooltip.

I found the way to reproduce this error on my system:

1. run 'rm -rf ~/.thumbnails'
2. run 'konqueror media:/' and maximize konqueror's window
3. goto directory with number of video files in konqueror
4. while konqueror generates thumbnails of video files move your mouse cursor over files with generated thumbnails and wait while big thumbnail will be generated in tooltip

What happens:
5. Konqueror crashes here almost every time

Here's my backtrace:

Can you still reproduce this on Edgy?

As far as I can remember I solved this problem by removing all "dot"-directories (not all but everything about kde) from my home directory.

I repeated the steps to reproduce the problem on my current system (Edgy) and did not get trash now.

The problem is solved, I think.

This sounds similar to the bug I am having in hardy. https://bugs.launchpad.net/ubuntu/+source/kdebase/+bug/205884
except that in my case konqueror does not 'crash' it just hangs, and becomes unresponsive.

Uninstall libarts1-mpeglib and libarts1-xine.
Even if we would find the code which causes the crash (which is doubtable), it would be highly unlikely that we can fix this crash without causing at least one new (also Arts, the KDE 3 sound server, is not used in KDE 4 anymore). I am closing this bug as Won't Fix, if you wish you can reopen it, but I don't see much use in it.
I hope it's the 2 packages from above that cause the crash :)
