Bug 240965

Created attachment 47765 [details]
New crash information added by DrKonqi

plasma-desktop crashes every time I try to start it, also after login. There were some Ubuntu updates on Friday 4.6.2010 (Ubuntu Karmic, amd64). I installed updated packages, but did not restarted my computer. When I turned it on again, plasma has been crashing.

When I start plasma-desktop from konsole with parameter --nofork, it works. Without this parameter it crashes every time. I hope this can help.

plasma works, but it has to be launched manually. No extra parameters needed. It just doesn't launch on logon and it seems, that it prevents some other applications from launching to. For example Kopete cannot be launched at all

that exception happens when an exception is thrown in an event handler. without knowing where this exception comes from (and it could come from any number of places) this report is not addressable.

This is the output from console. 
May it be a problem with drawing of some plasmoid? I use emailnotify, clock and cwp - but all these plasmoids work properly when running under plasmoidviewer.
There is also some problem with ibus, cwp is also unable to connect to ibus, but works even without it.

thanks for the follow up; now we know the issue: ibus, an input method tool. are you using the kimpanel plasmoid? if not, then it's not a plasma issue and a general system configuration issue. if you are using the kimpanel plasmoid for multi-byte input, then it -might- be a problem it is triggering (though the issue still remains a configuration issue on the system, but perhaps something kimpanel could handle better).

I'm not using kimpanel (but packages ibus-qt4, libibus-qt1 and plasma-widget-kimpanel-backend-ibus are installed - they probably are part of the default karmic installation or were added as a dependency of other packages that I installed manually). I use only emailnotify and cwp plasmoids (and some other installed in kubuntu by default). I also don't use multibyte input (just czech and english in the default system encoding UTF-8). 

Now ibus is not running (at least "ps -A | grep ibus" returns no result. 

When I tested my plasmoids under plasmoidviewer, they reported problem with ibus, but worked properly.

Today I installed plasma-desktop update and removed packages ibus-qt4 and libibus-qt1 (just to discover if ibus was causing problems). Plasma still crashes, but I would say it's now in different function. 
Line "FrameSvg::resizeFrame: Invalid size QSizeF(-3, -3)" seems to me that there can be a problem with resizing frame (??)

Is there a way how to manually disable selected plasmoids? - just to try start plasma without them. plasmoid-viewer runs plasmoids with different size than plasma-desktop, maybe some plasmoid has a bug in calculating it's size. But still plasma should do range-checking of such arguments to be more robust and prevent crashes of the whole desktop.

I attached gdb to running plasma and "catch throw".

Here is stack when plasma crashed. Hope it can help.

Hello Everybody

OS: Kubuntu 10.10 along with KDE 4.5.1.
My workspace sometimes crashed at start-up. Details: see report below.
Today, I managed to find at least an effective "workaround", as follows:
Alt F2 > Konsole (Terminal) > sudo mc > (password) > renaming ./kde to
something like "kde.old" via F6 > exit > CONTROL-ALT-DELETE > restart > as a
result a new, refreshed workspace has appeared which keeps working at every
start up.
Respectfully yours,
Bas Roufs.

Bug report generated today before finding the workaround.

*** Bug 271086 has been marked as a duplicate of this bug. ***

finding why the exception is thrown would be pretty critical to fixing this; likely this is the "exception in event handlers" bug from kdepimlibs things that has already been tracked down, but to know for sure on this an dhte many dupes would require some further work.

comment #21 is an unrelated (and fixed) bug.

Is this still valid with KDE 4.8.3 or trunk?

Hello! Plasma 4 was replaced by Plasma 5 four years ago by the KDE community. In that time we have made great strides in stability and functionality. We are closing all Plasma 4 bugs as most of them are no longer applicable to the new frameworks Plasma 5 is built upon. If you could, please re-test with the latest version of Plasma 5, and submit a new bug to "plasmashell" if you continue to have an issue. Thank you!
