Can you please attach a complete crash log? See <http://webkit.org/quality/crashlogs.html> for details. Based on the partial backtrace you provided, it appears that this crash is inside VLC itself which would almost certainly indicate that this is not a WebKit bug. The full crash log will help confirm this.
Created attachment 25420 [details] Crash log
Based on the backtrace that definitely looks like a VLC bug. I can't see any way that WebKit could be responsible for that. Please report it to the VLC developers.

Although the files can be shown in * VLC (Version 0.9.6 Grishenko (PowerPC)) * Firefox (Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.5; de; rv:1.9.1b1) Gecko/20081007 Firefox/3.1b1) * Camino (Version 1.6.5 (1.8.1.18 2008111212)) This is why I thought it could be WebKit related.
It is of course possible that it is somehow WebKit's fault, but there's nothing in the crash log to suggest it. The crash is on a secondary thread that VLC has created, and is entirely within VLC code.
