Comment 16 for bug 852485

I've removed sabayon (dpkg --purge sabayon). I have even done a reboot then. However the problem remains. I've attached the whole .xsession-errors file (I've tested with a totally new and "clean" user). I've tested memory with memtest for a while at least, as I thought; no problem has been found. However there is one thing, I don't know if related or note, but here it is:

I often see during package install/upgrade/etc:

Note that '/usr/share' is not in the search path
set by the XDG_DATA_HOME and XDG_DATA_DIRS
environment variables, so applications may not
be able to find it until you set them. The
directories currently searched are:

- /root/.local/share
- /usr/share/kde-plasma
