KTorrent crashed when I booted up my computer and it was automatically restored by session management. The only unusual thing was that network was offline.
Comment 2 Dario Andres 2009-09-27 13:54:03 UTC 
@Jos: this looks related to bug 192419 / bug 157850 (some KDEDIR KDE3/KDE4 mismatch causing khtml to load an incompatible file from a KDE3 dir...). Did you changed something in your environment vars ? It is strange that this happens when running a KDE4 app like KTorrent3.
Thanks
Comment 3 Joris Guisson 2009-10-15 19:54:25 UTC 
Reassigning to kdelibs, IMHO khtml shouldn't crap out when there is a version problem with some default css file.

ktorrent (4.0.4) on KDE Platform 4.5.2 (KDE 4.5.2) using Qt 4.7.0

I used ktorrent 4.0.3 in Fedora 13, and also 14 release.
 I have updated ktorrent 4.0.4 from fedora test repository - the error also is shown after start.

[Comment from a bug triager]
I'm going to use this bug report as a new master as some applications keep crashing on some builds.

From bug 243251:
-- Information about the crash:
When I try to run KMail from KDE4 in KDE3, I see this in my terminal:
!!!!!!! ERROR !!!!!!! - KHTML default stylesheet version mismatch. Aborting.
Check your installation. File used was:
/opt/kde3/share/apps/khtml/css/html4.css. Expected STYLE_VERSION 1

*** KMail got signal 6 (Crashing)

It seems there are some issues with environment settings when running certain
KDE4 apps inside KDE3.

It should be possible to run KDE3 and KDE4 apps side by side in either
environment transparantly.

The crash can be reproduced every time.
