Description michael 2004-04-23 23:27:07 UTC

Version:            (using KDE KDE 3.2.2)
Installed from:    Debian stable Packages
OS:          Linux

While deleting messages, I hit on a message that caused an immediate crash. (See backtrace below) The worst thing is that when I restart, it is of course back on the same message so it crashes a second time. PS, the backtrace window didn't popup on the second crash.

(Message is here as an attachment)

Email message which causes crash

Actaully, it seems that the crash occurs when i move from another message in
the message list to this one.  I can replicate the error by selecting the
message above it, and then arrowing down to this message

Comment 2 michael 2004-04-23 23:41:49 UTC

Removing the message from inbox/cur fixed the problem, albeit it then lost some of it's memory of which messages were viewed to date etc..
Moving it back to the inbox/cur caused it to crash again..

Comment 3 Ingo Klöcker 2004-04-24 12:38:11 UTC

Thanks for the bug report. I can reproduce the crash with the Qt movies example. So it's a bug in the Qt libraries. I'll send a bug report to Trolltech.

I'll attach the (broken) GIF which can be used to reproduce the crash. Note that tests indicate that the crash doesn't happen everytime.

Opening this GIF in Konqueror or KMail crashes those programs

Comment 5 Tobias Koenig 2008-04-25 09:06:57 UTC

I can't reproduce the crash with konqueror from 3.5.9 or 4.0 anymore.
The gif is invalid by the way...
