Description Manuel Gaus 2008-04-01 14:38:16 UTC

Version:            (using KDE 3.5.8)
Installed from:    Ubuntu Packages

After having created an extensive list auf tasks with repetitions and so on... kontact refuses to launch and exits with a sigsev. On my last kontact session i have seen korgac failing with a sigsev as well. 

Here is a Backtrace of the crash:

The parts of Kontact seem to start well independently, except korganizer and korgac wich produce sigsevs when launched from konsole

when korganizer is started first korgac crashes then korganizer crashes

Comment 1 Allen Winter 2008-04-01 15:09:00 UTC

this is a well known bug about binary attachments.
the bug is deep in the 3rd party libical library.

try starting korganizer by itself first, find 
calendar events and to-dos with binary attachments
and remove the attachments from them.

then restart.

i am absolutely certain to have no binary attachments for callendar events or 
to-dos.

> try starting korganizer by itself first


that does not work as the traceback of korganizer indicates, which i added to 
the bugreport.

I would like to do so, but without a running korganizer i can hardly access 
those events and to-dos.

Is there another way to deal with the problem?

regards, and thanks for your patience :-)

erm... not so certain actually... I created a to-do entry from an email, this 
added a binary attachment to the to-do entry.

luckily the .ics files i found under /home/$user/.kde/share/apps/korganizer 
are human readable. So I found the violating entry, and deleted it. 
Everything is fine again.

Thanks a lot for taking care of this nonetheless...

regards, 

Manuel
