Description Johann Höchtl 2012-03-31 18:40:31 UTC
After resume from Hibernate, some KDE apps crash.

The apps are:

KDE Daemon
KDE Activity Manager
KMix

Sometimes, none crashes, sometimes two, sometimes all three. Most of the time it's KMix.

I am using Kubuntu 11.10 with
https://launchpad.net/~kubuntu-ppa/+archive/backports
enabled (thus parts of KDE 4.8.1)

I would happily try to narrow down the problem and if it is related to a mixture of KDE 4.7 / 4.8 libs, my hardware (though it seems no other deamons or eg X crash) or somehow related to KDE 4.8.x
Comment 1 Johann Höchtl 2012-03-31 18:46:55 UTC
It seams more apps are involved. I collected this backtrace:


Application: bluedevil-helper (0.1)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-17-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
<In detail, tell us what you were doing  when the application crashed.>

The crash can be reproduced some of the time.

-- Backtrace:
Application: Bluetooth File Receiver Helper (bluedevil-helper), signal: Segmentation fault
