*** Bug 210739 has been marked as a duplicate of this bug. *** - Can you reproduce this crash at will ?
I have been tried to reproduce it with your steps but I failed.
Here using:
Qt: 4.6.0 (kde-qt master commit 747ff8e6ef6f5a1163dfa75bc9ac4755ce7083d1
Date: Tue Dec 15 11:58:13 2009 +0100)
KDE Development Platform: 4.3.82 (KDE 4.3.82 (KDE 4.4 >= 20091211))
kdelibs svn rev. 1063229 / kdebase svn rev. 1063229
on ArchLinux i686 - Kernel 2.6.31.6
(Note that some of the times I got bug 210146 (same bt), but now that kde-qt includes the fix, I don't get crashes at all)
Yes, it is crashed every time, when I tried and restart KDE. After crash, Calendar is not available, until you delete Digital Clock widget and add new one. But my version is Beta1 (4.3.80) from Mandriva repositories, so it can be already fixed in svn (I am waiting for Beta2 or RC to try). Using: Desktop View (not Folder View). *** Bug 219371 has been marked as a duplicate of this bug. *** I managed to reproduce the issue here using:
Qt: 4.6.0 (kde-qt master commit 747ff8e6ef6f5a1163dfa75bc9ac4755ce7083d1
Date: Tue Dec 15 11:58:13 2009 +0100)
KDE Development Platform: 4.3.82 (KDE 4.3.82 (KDE 4.4 >= 20091211))

on ArchLinux i686 - Kernel 2.6.31.6
Steps to reproduce:
---
- Unlock your Plasma widgets
- Run "kdialog --passivepopup foobar 20" from Konsole (or force any other "lengthy" passive notification to appear)
A notification appears in the systray
- Drag that notification (from its title) to the desktop
The notification appears into the desktop, no errors yet.
- Drag the same notification (using its title) to a different location into the desktop
The notification is moved but ~its content is erased~...
- Remove this empty extender container using the remove button in the applet handle.
Plasma crashes.

It seems that this also happens if using other extenders (the Calendar in the clock widget, or the one in the Battery widget) Created attachment 39537 [details]
