Package: konqueror
Version: 3.1.5-1
Severity:important
I've been getting a lot of mysterious segfaults from konqueror, and haven't
had much luck finding out what's causing them.
This time, I followed Dominique Devriese's advice, installed his debug
versions of konqueror and kdelibs4, and ran konqueror inside of gdb, to get a
backtrace.
Here are the contents of konqueror-crash-s0QTsc.log, which shows which pages I
was browsing when the segfault occured.

In any case, surfing at Ars Technica's forums at
http://episteme.arstechnica.com/6/ubb.x has caused frequent segfaults of this
kind for me, as that particular site uses some complex javascript and css
features that aren't frequently used elsewhere (and cause some rendering
problems in Konqueror as well.
Without further ado, here's the backtrace. I can reproduce this segfault
fairly easily on my machine, and I know that other people aren't getting them
nearly as much. So if you need more information, (I'm trying to feed
konqueror through valgrind at the moment) let me know.
Program received signal SIGSEGV, Segmentation fault.
