Package: konqueror
Version: 3.1.5-1
Severity:important
I've been getting a lot of mysterious segfaults from konqueror, and haven't=
=20
had much luck finding out what's causing them.
This time, I followed Dominique Devriese's advice, installed his debug=20
versions of konqueror and kdelibs4, and ran konqueror inside of gdb, to get=
a=20
backtrace.
Here are the contents of konqueror-crash-s0QTsc.log, which shows which page=
s I=20
was browsing when the segfault occured.

In any case, surfing at Ars Technica's forums at=20
http://episteme.arstechnica.com/6/ubb.x has caused frequent segfaults of th=
is=20
kind for me, as that particular site uses some complex javascript and css=20
features that aren't frequently used elsewhere (and cause some rendering=20
problems in Konqueror as well.
Without further ado, here's the backtrace. I can reproduce this segfault=20
fairly easily on my machine, and I know that other people aren't getting th=
em=20
nearly as much. So if you need more information, (I'm trying to feed=20
konqueror through valgrind at the moment) let me know.
