I couldn't figure out how to reproduce the XDG_DATA_DIRS=: case, unless it was a corrupted
/var/cache/desktop-profiles/activated_profiles file (the file is 0 sized now, don't know if it contained anything before).
Should there be some sanity checks in KDE / desktop-profiles scripts to check that XDG_DATA_DIRS make sense?
i.e. that it refers to at least one directory that exists.
