were you moving things between, say, the desktop and the panel? or between two activities when zoomed out?

I think I was just moving plasmoids on the desktop, one over another. I know this is not enough information but since I have a backtrace I just want to report this.
Comment 3 Dario Andres 2009-05-29 15:01:38 UTC 
Yeah, so it is probably a duplicate of bug 192589. Also, backtrace on bug 187251 comment 6 is the *same* (which is probably also a dupe of bug 192589)

Comment 5 Marco Martin 2009-06-02 21:35:31 UTC 
uhm, looks like focusapplet on a deleted applet is called before appletdestroyed is called
Comment 6 Aaron J. Seigo 2009-06-05 07:07:06 UTC 
well, reason i asked if a plasmoid was moved between containments is because there was a bug until the other week (because i fixed it ;) that left the focused applet pointer in a bad state when a plasmoid was moved between containments, which in turn led to crashes.

if it was just one plasmoid moving over another, i'm not sure how that would result in the focussed plasmoid being deleted? it would be a lot easer to accidently move it into a panel and re-hover the other applet.
Comment 7 Ivan Čukić 2009-09-14 18:51:21 UTC 
Since no additional information is provided, and it looks like the same focus issue like bug 185647
