Summary: KDED crashes with newest Project Neon
Product: [Frameworks and Libraries] kdelibs Reporter: Stephan Diestelhorst <stephan.diestelhorst>
Component: kdedAssignee: Unassigned bugs mailing-list <unassigned-bugs>
Status: RESOLVED NOT A BUG    
Severity: crash

Platform: Ubuntu   
OS: Linux

Description Stephan Diestelhorst 2012-01-12 13:41:28 UTC
Application: kded4 ($Id$)
KDE Platform Version: 4.7.98 (4.8 RC2+ (4.7.98)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:

Logging into a Project Neon session, after having used standard KDE 4.7.4 before.
Worked with yesterday's snapshot.

- Unusual behavior I noticed:

Desktop effects were not working. How can I check the proper activity version? Using the PLasma Neon (previous) session in kdm. Maybe that had some old (yesterday's?) stuff lurking somewhere.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Aborted

Seems to work again after system shutdown and restart. Might very well have been the session creep mentioned.
