Description Martin Klapetek 2012-02-01 17:56:53 UTC 
Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.00 (4.8.0) (Compiled from sources)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:

The weird thing is, that I removed the chat plasmoid from my panel few hours ago. Now when I started chat with someone who was in the plasmoid, plasma went down.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault

The weird thing is, that I removed the chat plasmoid from my panel few hours
ago. Now when I started chat with someone who was in the plasmoid, plasma went
down.

I think that's actually key to this.

If this plasmoid is started, you'll create all the telepathy objects
I think ConversationClientObserver is "leaked", as the observer hold a reference to the clientRegistrar which holds a refernece ot the observer.

So when you close the plasmoid these both stick around. When you delete the plasmoid TelepathyTextObserver is null, and the ConversationClientObserver::m_parent is now a dead pointer.

Fixes needed:
 1) fix the circular dependency in the ConversationClientObserver (move registrar to TelepathyTextObserver)
 2) use a QWeakPointer on m_parent (and check before using)
 3) rename one of these classes so it's not really really confusing.

Damn, I didn't notice this bug was for the plasmoid till now. 

I did recall it had an issue where if you add the plasmoid to the desktop, then delete and re-add, it complains that KDE.TextUi.ConversationWatcher is already registered. So I suspected that they might not be getting deleted properly, but I didn't peruse at the time because that class was going to get completely overhauled soon anyway. 

Plus I tested this mostly in plasmoidviewer so it didn't really come up much.

Move registrar from ConversationClientObserver to TelepathyTextObserver

Right, I did as David suggested. Martin, can you please check if this patch fixes it?
Comment 4 Lasath Fernando 2012-02-06 12:34:03 UTC 
Right, that seemed to do it. I'm closing this bug.
