Comment 1 Dario Andres 2009-12-04 13:39:01 UTC

The crash seems related to the Python widgets so I guess this "Console Plasmoid" is written using that Language.
- Have you tried to repeat the issue to check if Plasma crashed again ?
Thanks

Comment 2 Aurélien MANCA 2009-12-04 14:11:52 UTC

I confirm this plamoid bug. It crashed again.

Comment 3 Dario Andres 2009-12-05 21:31:29 UTC

- Where did you got this "Console" widget ?
Thanks

Comment 4 Aurélien MANCA 2009-12-06 08:48:57 UTC

I got it there : http://www.kde-look.org/content/show.php?content=108120
