Comment 1 Dario Andres 2009-09-18 15:58:19 UTC 
Mh, weird, it seems like a KIO bug. Thanks
Comment 2 Michael Pyne 2009-09-18 20:45:41 UTC 
Does this still occur if you run Kopete from a terminal like this?

unset MALLOC_CHECK_ ; kopete

It is important to remember that the "MALLOC_CHECK_" has a _ at the end as well.
Comment 3 Fabio Puddu 2009-09-23 14:56:00 UTC 
I've run kopete for a few days as you asked and it seems not to crash anymore, but since the crashes seemed to be random I cannot be sure that it resolves the problem.
Comment 4 Michael Pyne 2009-09-23 22:45:24 UTC 
Well if you manage to reproduce a crash (probably it will be SIGSEGV instead of SIGABRT) please re-open, otherwise I'm assuming this is a known issue we're having with glibc 2.10.1.

Comment 5 Fabio Puddu 2009-09-24 19:36:05 UTC 
I am reopening the bug because today it crashed again after running it from a terminal with
unset MALLOC_CHECK_ ; kopete
This are the terminal data after the crash.
