Application: plasma-desktop (0.3) KDE Platform Version: 4.4.85 (KDE 4.4.85 (KDE 4.5 Beta2)) Qt Version: 4.7.0 Operating System: Linux 2.6.32-22-generic i686 Distribution: Ubuntu 10.04 LTS -- Information about the crash: - What I was doing when the application crashed: Plasma starts. Everything ok, but a small empty window appears. It is resizeable, but it has no content, meaning it holds the graphic of what it is above it and does not update. If I close it (alt+F4, taskbar or "X") plasma crashes. When it reloads, the blank window reappears. I have checked if I have any strange plasmoid running but not showing, but I do not have any. This is the "xprop" output _NET_WM_ICON_GEOMETRY(CARDINAL) = 30, 774, 225, 28 WM_STATE(WM_STATE): window state: Normal icon window: 0x0 _NET_WM_ALLOWED_ACTIONS(ATOM) = _NET_WM_ACTION_MOVE, _NET_WM_ACTION_RESIZE, _NET_WM_ACTION_MINIMIZE, _NET_WM_ACTION_SHADE, _NET_WM_ACTION_MAXIMIZE_VERT, _NET_WM_ACTION_MAXIMIZE_HORZ, _NET_WM_ACTION_FULLSCREEN, _NET_WM_ACTION_CHANGE_DESKTOP, _NET_WM_ACTION_CLOSE _KDE_NET_WM_FRAME_STRUT(CARDINAL) = 2, 2, 21, 2 _NET_FRAME_EXTENTS(CARDINAL) = 2, 2, 21, 2 _NET_WM_DESKTOP(CARDINAL) = 2 _NET_WM_STATE(ATOM) = The window can be moved to another desktop, so it's only marginally annoying, but a fix would be apreciated. I have Kubuntu 10.04 with KDE backports ppa enabled and my plasma version i 4.4.85. Everything started after an update where also plasma was involved! Thanks!!! The crash can be reproduced every time. -- Backtrace: Application: Plasma Workspace (plasma-desktop), signal: Aborted [Current thread is 1 (Thread 0x444f8430 (LWP 5516))] Thread 2 (Thread 0x4d671b70 (LWP 5518)): #0 0x43d490d3 in ??

I found out the origin of the empty window, but it's closure still trigger the crash in plasma. It is due to the claws-mail "trayicon" plugin which 1) inserts it correctly in the tray notification area, but 2) creates this empty window, too. Unloading this plugin removed the empty window.
This bug is still there. I am using kde 4.4.4 on 10.04. I guess using any non-native-qt which goes to sys tray triggers this bug. Invoking google-dekstop or checkgmail or vlc player will start respective apps as well as a small window (one for each app)as discussed in the above bug report. The small window disappears as soon as respective apps are closed. Closing these small window crashes plasma-desktop

The small empty window disappears as soon as respective apps are closed. Closing any of these small empty window crashes plasma-desktop. Also if there are more than one of these windows they tend to group under task manager grouping rule. So, they are registered under same window ID I guess.
I can confirm, this bug is still there. Every time I open a new application that put a new tray icon in the system tray (like skype or kontact) a very small window opens. The background color of the tray icon is black and the small window shows the background instead. It's a very annoying bug...

The bug status is wrong, the bug is still there, I think should be reopened as unresolved.

The small window is caused by a Qt 4.7 bug, and has been resolved in latest Qt from 4.7 branch. See http://bugreports.qt.nokia.com/browse/QTBUG-10809. I don't know if the crash is directly related to the bogus small window, or if it needs to be resolved independently.

in case anybody ends up looking at the backtraces and wondering what this has to do with a DataEngine: the real issue is that the process is getting an XIOError and the app is attempting to wind down in an unclean state which triggers problems elsewhere. but those parts of the backtraces have zero to do with the problem. posting more of the same backtraces doesn't help illuminate new issues, either, so reporters who have been diligent in doing so (thank you) can stop doing so :)
There are Kubuntu packages carrying the fix mentioned in comment 14 available at <https://bugs.launchpad.net/kubuntu-ppa/+bug/614699>. It also fixes the broken embedding of rdesktop in krdc in case such a bug was dup'ed here.
I can confirm that this fix: https://bugs.launchpad.net/kubuntu-ppa/+bug/614699 actually worked. I had empty windows opening with several applications, now it is gone.
Similar windows appear when I launch VLC (tray icon should be enabled in vlc config) or Truecrypt (maybe other apps). When closing that windows, plasma crashes. KDE 4.5.0 final release. Kubuntu 10.04 x86
@BrainFucker: Try the fix linked from comment 21.
(In reply to comment #24) > @BrainFucker: Try the fix linked from comment 21. Yes, this solved the problem. Thank You.
it solves problems also for amsn tray icons and all others thanks
