Bug 301455

Application: kded4 ($Id$)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Logging to KDE.
- Unusual behavior I noticed:
recently seeing consistent vairous programs crashing either "Before or currently" especially during log in of computer. It seems to not effect the operation of the laptop, but the laptop does slow significantly regularly in the past 3 weeks. A notice of the a program crashing recently or in the past is reported. Various programs crashing. This Bug Report program is not acting correctly, for example, I could not choose a similar crash report in the previous window of this Bug Report program.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
