Can you reproduce this bug?
Comment 2 Alex Fiestas 2011-01-20 15:04:30 UTC
Another "ping", can you reproduce the crash? is it still happening?
Comment 3 Christoph Feck 2011-01-21 00:26:13 UTC
I think it was caused by having BlueDevil module in kded4 disabled, but Obex module enabled. I disabled both modules to avoid the crash.

Now enabling only Obex module does no longer crash, so I guess it is fixed.
Comment 4 Alex Fiestas 2011-01-21 00:33:15 UTC
Ok then, thanks for the feedback.
