thanks for the suggestion, i'll give it a try.
i suspect the culprit is one of the mono dependencies of keepass. reason
is, keepass does not use the native window manager, it's interface looks
very windows-like (as in ms windows).
i can usually fix the issue by purging keepass2. just removing
i just can't seem to reproduce this reliably.
the problem also occurs after removing (not purging) keepass2. the
update-mime-database command does not help but killing X and logging in again
seems to provide a temporary fix.
i attached a copy of my .xsession-errors.

its possible that its not keepass fault but some general problem when the

does sudo update-mime-database /usr/share/mime fix the issue?
maybe try removing /usr/share/mime/packages/keepass2.xml and then update the
database again.
(reinstall it with sudo apt-get install --reinstall
