Description Vikram Karandikar 2008-02-28 05:29:26 UTC
Version:           0.0 (using 4.0.1 (KDE 4.0.x >=20080201) "release 12.6", compiled sources)
Compiler:          gcc
OS:                Linux (i686) release 2.6.22.17-0.1-default

I don't see this crash often but this crash does not stop KDE4 from starting.
i also saw a similar crash logged in the bug repo but the stack trace is different so i am again submitting this crash.

Comment 2 Sebastian Sauer 2008-03-10 01:26:42 UTC
Hi Vikram,

does this still happen for you with KDE 4.0.2? If yes, could you please install the debug-packages, so kdebase-dbg rather then kdebase, and provide a more useful backtrace? Thanks in advance :)

probably related are;

Comment 3 Austin English 2008-03-26 09:32:34 UTC
Still happens for me in kde 4.0.2. I was running the wine conformance test, which left my resolution messed up. Restarting X now crashes in plasma each time on boot. I've tried installing kdebase-dpg as well as libplasma-dev, but a backtrace is still not generated.


This is in the kubuntu hardy beta.

Comment 4 Vikram Karandikar 2008-03-26 13:27:47 UTC
hi,
   i tried with KDE 4.0.2 and i can still see the plasma crash.
   my problem is when the crash occurs the bug report tool comes up but my login session restarts immediately.
   though i have installed debug libraries i am not able to collect the BT.

   Another strange thing i am observing is, after online update using openSuse updater, i see frequent crashes when i
   immediately restart the OS. As above i am not able to collect BT.

   How can i help you more?

Thank you,
Comment 5 Davide Fabbri 2008-03-27 16:07:20 UTC
I got the same crash at startup (every time) after upgrading to kde 4.0.2 with kubuntu hardy beta!
Comment 6 Jonathan Ford 2008-03-30 15:45:48 UTC
I get a similar crash on logging into KDE on Ubuntu Gutsy (with the Hardy 4.02 packages installed). At startup Plasma crashes and then the rest of the interface fails to load (presumably because there is no "backup" to Plasma?). I can still launch programs, however (I'm writing this on Konqueror, everything else looks OK too).
Comment 7 Austin English 2008-03-30 20:37:28 UTC
I ended up backing up /home, rm -rf ~, then logging in. That solved the issue. Presumably something in .local/.kde is causing the problem, but I didn't track it down further.
Comment 8 mtweak 2008-03-31 03:58:38 UTC
The "fix" is to delete ~/.kde4.  It worked for me.
Comment 9 Aaron J. Seigo 2008-03-31 04:01:50 UTC
@mtweak: and with it all your other settings, application data, etc. deleting your entire $KDEHOME is a very blunt hammer to apply to a problem such as this. removing share/config/plasma-appletsrc in this case would've been enough, as would have making sure all your plugins were actually compiled against the version of libplasma that was installed.
Comment 10 Markus Grob 2008-04-08 00:13:30 UTC
WFM with OpenSuse 10.3 with KDE 4.0.3 and Qt 4.3.4. 
Do you really have necessary things in .KDE4 which is thought for testing now only?
Comment 11 Dario Panico 2008-04-28 20:05:43 UTC
i don't know if i have the same issue or another but i prefer not to open a new bug. I'm on kubuntu 8.04 with kde built via kdesvn-build.
Here is the backtrace i got:

Comment 12 Andrey Borzenkov 2008-05-11 19:19:42 UTC
I have similar crash on Mandriva cooker with KDE4 4.0.72. I cannot reproduce it using clean account, but under my account it crashes always even after removing ~/.kde4

Degug-inofs of plasma crash
Comment 16 Thomas Kamps 2008-07-17 17:41:00 UTC
For me plasma crashes with 4.1rc1 again. See commend above for debug-infos
Comment 17 Aaron J. Seigo 2008-07-17 20:44:54 UTC
Thomas: yes, you have binary incompatible applets
Comment 18 Thomas Kamps 2008-07-18 16:04:41 UTC
To test, if there are problems with my applets, i deletet plasmarc and plasma-appletsrc But plasma still crashing.

Comment 22 Rik 2008-09-12 21:42:05 UTC
I think I had the same problem. A bit frightening at first, but I was able to solve it simply by removing the files share/config/plasma-appletsrc and share/config/plasmarc. 

I guess this problem has already been been identified and fixed (or worked around) but I have backed up the removed files so if it is of any interest, I can provide more information. 

Before I could install the updates that lead to this problem I had to remove some 'kde base debuginfo' because of a dependency problem so I'm afraid that I wont be able to provide a useful backtrace.

After this first hiccup I must say that I'm very pleased with the look and feel of the updated KDE/plasma.

Keep up the good work ;-)     
Comment 23 Maxi Schimmel 2008-09-20 06:43:43 UTC
Recently update my KDE to 4.1.66 from opensuse repos and Plasma crashes on startup and if I run it manually.

Removing ~/.kde4/share/config/plasma* solves this inconvenient (but lost my configurations :( ).

The debug info is this:

Comment 24 Roxy Road 2008-09-20 08:15:30 UTC
I changed first-/second boot (devise?) (BIOS) and after boot it shows 
this icons (I think there're of the Systray) and the Background turned 
blue, next there were only the Crashmanager.
Comment 25 Vikram Karandikar 2009-01-11 07:25:57 UTC
Hi,

Now i am using 4.1.3 (KDE 4.1.3) "release 66.2" on
openSUSE 10.3 (i586) and i have not seen this crash in plasma at all.
