Comment 1 Thomas Malkus 2010-11-21 17:01:08 UTC

After removing the RemberTheMilk plasmoid from the desktop, the desktop is started normally. So I think the reason for this crash is the RememberTheMilk plasmoid.

Comment 2 Dario Andres 2010-11-21 18:35:27 UTC

[Comment from a bug triager]
Indeed, this is a bug in the RememberTheMilk plasmoid. The issue is being tracked at bug 202918. Merging.
Thanks
