This is with r829290. Caveat: my nsplugin installation is hosed (likely due to 'yum remove'ing the i386 version), though I'm unconvinced that would directly cause this. (I'll likely try a complete rebuild of libs+base later, after I manage to submit this amidst konq crashing on me :-).)
Comment 1 Matthew Woehlke 2008-07-08 17:06:13 UTC
...silly karma :-), unconfirming until someone else can reproduce
Comment 2 Christophe Marin 2008-07-08 18:00:06 UTC
I can't reproduce using Konqueror from trunk (kdelibs rev. 829304).

Comment 3 Christophe Marin 2008-07-08 18:07:51 UTC
Note : the bt is the same as the one in bug 164348.

Comment 5 Maksim Orlovich 2008-07-08 18:23:14 UTC
This one may be slightly different, actually, since it doesn't have to do with backwards navigation. They just share a crash point...
Comment 6 Maksim Orlovich 2008-07-08 18:24:50 UTC
as above..
Comment 7 Matthew Woehlke 2008-07-08 22:28:24 UTC
still reproducible in r829547 after clean builds of libs and base (which seems to have fixed the nsplugin problem also). Note: I don't get the crash *every* time, but it feels like it dies more often than not.

I can reproduce with a clean session, i.e. launch konq (don't restore session if asked), paste the address and hit 'enter' to load the site, usually but not always -> SEGV.

I'm on Fedora 8 on an x64 (KDE4 built from sources as in the report headers)

http://www.sagemath.org (from bug 164384) doesn't crash for me

Comment 9 Oliver Putz 2008-08-12 07:59:47 UTC
Not really reproducible, but I managed to crash konqueror on this page at least once. (I clicked on the title (to go to the page itself) and then hit the back button which made konqueror-4.1.0 crash for me). At least for me, the page from bug #168954 crashes with the same backtrace, but far more reliably.
