Comment 4 Dario Andres 2009-07-16 17:05:08 UTC

This is most likely related to the backtrace in bug 193364.
Can you reproduce the crash at will ?
Thanks

Comment 5 Balcaen John 2009-08-12 19:43:36 UTC

i'm not able to reproduce it again currently (neither bug #193364)
I'm going to try again this week.
Regards

Comment 6 Dario Andres 2009-08-12 20:18:05 UTC

Thanks, merging.
