Description Belomir 2012-02-02 10:25:18 UTC

Application: kded4 ($Id$)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- Unusual behavior I noticed:

Ones it happend and become permanent: kdeinit4 crash after while on every log in dureing loading programs and filling systray with applets and indicators. hdd is fully used in this case sometimes for cursor lack or even stop (may be #12309 bug).
Systray loses some of its configs like what to hide or what to show etc.
Not so crittically but strange and rather annoying.

The crash can be reproduced every time.

-- Backtrace:

New crash information added by DrKonqi

kded4 ($Id$) on KDE Platform 4.7.4 (4.7.4) using Qt 4.7.4

new info for this bug:
- What I was doing when the application crashed:

Just read web page in firefox. Dureing scrolling cpu usage come up to 100%, kde freeze except for mouse cursor and I get the kdeinit4 segfault.

After that systray reloads itself.
I've got a message from muon about some upgrades available (there was not before crash) and lotls of empty icons that doesn't react on right mouse click.
In systray hide/show preferences thay displayed like 1::/org/kde/systemnotifieritem/1 — this elements sometimes appears in systray after plasma crash until relogin.

Dureing posting this message systray reloaded automatically and strange itemes gone.

kded4 ($Id$) on KDE Platform 4.7.4 (4.7.4) using Qt 4.7.4

Some new information.
- Unusual behavior I noticed:

Obviously this crash is not associated with RSI break, kdestart (after login) or muon updates. It can crash randomly dureing working with LibreOffice.

With some of this crashes irkick (as it formely known) can't configure remote controllers because of the kded is not executed.

Continuing investigating…
