Comment 1 Elias Probst 2011-06-08 16:02:26 UTC 
I think I found the way now to reproduce this crash.

→ Open Empathy + connect your accounts
→ Open a chatwindow of one of your contacts in Empathy
→ Open KDE Telepathy Contact List
→ Doubleclick on the same contact, you have already opened an Empathy chatwindow for
→ Quit Empathy
→ KDE Telepathy Contact List crashes
Comment 2 Elias Probst 2011-06-08 16:04:17 UTC 
One special thing here:
When doubleclicking the contact in the KDE Telepathy Contact List, you have already opened a chatwindow in Empathy for, the Empathy chatwindow is raised in foreground and not a KDE chatwindow is displayed.

Maybe this happens by design, maybe this fact helps solving this crash - it's just for information :)
Comment 3 Elias Probst 2011-06-08 16:16:05 UTC 
It seems this probably rises another interesting bug:
Although Empathy isn't started, Empathy's chatwindows are opened (by starting Empathy in the background) when clicking on a contact in the Telepathy KDE Contact List.

I don't know whether this is a bug or a feature. If it's a bug, I'll open a new report for it - I just need to know :)
Comment 4 Martin Klapetek 2011-06-08 21:30:25 UTC 
"Empathy's chatwindows are opened"

That's not really a bug. It simply uses whatever handler is present (ie. it's the design). Although I thought this should not happen when the preferred handler is set (which KDE Contact list does). Please open a new bug on this one.
