I would suspect it should not be sufficient. Virtually all other files in
/opt/trinity/bin are world executable. Maybe it doesn't need to be because
r14-xdg-update calls it at session start? Needing it for each session start
seems to be why Kate's suggestion didn't stick.

Why it only happens with one user would suggest it would not be a problem with
/opt/trinity/bin/kxdglauncher permissions, which dates to last July here. Maybe
take a look at /etc/group to see if all users are in any groups that might be
relevant to a TDE session. If you navigate through $HOME, is everything owned
and grouped by the problem user?

Is there anything obvious in /var/log/tdm.log?

I cannot reproduce xsession errors on the system I tested, but do see a few in
.xsession-errors. Do your errors vanish if /opt/trinity/bin/kxdglauncher is made
world executable? Likely this needs to goto the trinity-devel list if it doesn't
help, or maybe goto IRC and ask Slavek about those permissions.
