KDE crashing immediately after logging in

[Guest]

Hi guys,

I am running into this this problem that immediately after logging in, KDE will immediately crash upon showing the splash screen. I have tried 1) Remove my ~/.kde folder and make sure my KDEHOME, KDEDIR, LD_LIBRARY_PATH are empty. 2) Re-install kde packages from synaptic, but neither one solved the problem. The really strange thing is that only one user account is affected and the other isn't. I suspect that I just need to clean the config files sufficiently and KDE4 will work again. Please let me know what else I could try, thanks!!

dmesg shows the following error

[ 5466.377912] kded4[15019] trap divide error ip:7f323fdd60df sp:7fff2d65b3d0 error:0 in libkdecore.so.5.5.0[7f323fb90000+2b7000]

Re: KDE crashing immediately after logging in

Hey,

I have the same problem. Apperently nobody else does. I looked up all over, but i did not find any answer. I was developing with KDE and tried some QML plasmoids with Plasma:eclarativeWidget.
Then i ran the new plasma-desktop. After i shut down my computer i could not start kde anymore.

hope anybody has an idea.
