Bug#643656: [plasma-desktop] KDE: applications vanishing from taskbar and icons not showing up in tray
Package: plasma-desktop
Version: 4:4.6.5-3
Severity: normal
--- Please enter the report below this line. ---
Last week one of my hard-disks lost connectivity and RAID array went down.
digikam and the the taskbar application died with a SIGBUS. So far this was expected (
it probably tried to read an open file, but filesystem went away).
After I fixed the RAID array and logged into KDE, and I had no taskbar/tray icons anymore.
So I clicked the Panel toolbox button on top right corner, and clicked add panel.
Surely the taskbar and tray area was back now.
However the tray area is not working anymore, I see the clock, and the standard KDE icons
(clipboard, kbd layout switcher, randrtray, mixer, bluetooth, etc.), but I don't see
pidgin's icon at all. Of course pidgin is running. The situation persists after logout/login, and reboot.
How can I debug why the tray is not working? Is there some debug information I could provide?
What is the name of the application that provides the tray area?
(in KDE3 I think it was kicker, don't know about KDE4).
The taskbar is misbehaving too, for example icedove keeps vanishing (have to run icedove to
get it focused again). Don't have a definitive testcase for it, but if I switch to another app,
and use it for a while, and then later (half an hour?) look for icedove its gone.
I checked dmesg and there is no segfault message about icedove there.
Still it could've died without logging anything to dmesg, will try to confirm with 'ps' that its still running,
the next time it vanishes.
