Did you have a folderview in panel? The bt shows that there was a list view, which is only present when the fv applet is in a panel. Or was the folderview applet first located in a panel, and then you dragged it out onto the desktop? Thank you!

That's the interesting thing, I had added a folderview to the panel, but subsequently removed it. I just wanted to see what it would look like in the panel. The actual crash didn't occur until a couple of minutes later, when trying to change desktop colors (And the folderview had already been removed from the panel).  I didn't drag it to the desktop, I deleted it from the panel.

Comment 5 Ignat Semenov 2012-12-23 15:47:41 UTC
Awesome, thank you for the input! The fact that folderview had already been deleted from the panel is very important.
Comment 6 Ignat Semenov 2012-12-23 17:54:06 UTC
Can you reproduce the crash every time (reliably)? Or is it spontaneous?

I've followed the steps you've described (add a folderview to panel, remove it, change colors) and the crash did not occur.
Comment 7 Ignat Semenov 2012-12-23 17:55:48 UTC
Is your desktop folderview or "Default Desktop" (a no icons containment)? Another user has reported this crash with a folderview as their containment, maybe your case is similar? Thank you!
Comment 8 Ignat Semenov 2012-12-23 18:28:33 UTC
OK, turns out:

1)Applet classes' destructor is invoked on removing an applet
2)ListView ownership is transferred to a QGraphicsScene, which is owned by an object of the Dialog class, and the Dialog object is not deleted on removing an applet.
Comment 9 wodencafe 2012-12-24 03:58:03 UTC
Hello Mr. Semenov,

My desktop is a default desktop, not a folder view desktop.
Do you still need me to attempt to reproduce this crash, or is this solved now?
Comment 10 Ignat Semenov 2012-12-24 09:56:52 UTC
Yes, this is solved now, and I've managed to reproduce it reliably when changing the Plasma theme.

Thank you for the valuable input, the key bit of information was that the applet needed to be deleted from the panel to trigger the crash.
