libkdecore.so.5.5.0 is broken (?)

[Thomas Karl Pietrowski]

after loging in I get back to the login screen and dmesg tells the following:

[ 464.235181] kded4[2145] trap divide error ip:7f8bebc340df sp:7fff405a6690 error:0 in libkdecore.so.5.5.0[7f8beb9ee000+2b7000]

I created a test user and was able to login to KDE again. Seems that our user profile somehow got messed up.

[Thomas Karl Pietrowski (thopiekar)]

haven't tried that.. can someone else confirm this, so we could close this bug.

I just backed up my home-folder and reinstalled kubuntu. When thinking
about all the up- and downgrades I made, this solution would be the
best, but the fastest definitly yours, rgbiernat.

I remember that I removed the .kde folder without changes.. Could you,
rgbiernat, remove the .kde folder from your home folder and check?

Thanks!

This problem took me hours to troubleshoot.

I also thought that the .kde folder was the one which prevented me from logging in. Renamed it. But without success.
This one eventually helped me - deleting the kde-cache for my user in /var/tmp as suggested here:

After that I could access my profile again without problems.
