Hello x2go people :)
i have a server running Ubuntu 11.10 with an x2goserver installation, version 3.0.99.10-0~434~oneiric1, and it is running well and stable.
We had some strange problems, though. We contacted a school, who would help us test the server under daily use, and made some test users for them, called "test-*their name*". When they, and i, tried to log into those users, the client would freeze, no error message or anything. On the server, the x2goagent would run amok, soaking up CPU power. The problem seems to occur only on users with dashes in their names.
Can anyone replicate this? it is quite strange

Hm, and I would have expected for it to be usernames with spaces to go havoc (those occur esp. in winbind-ed environments), since the x2go stack has a notorious underquoting of shell variables all over the place.

I can confirm this bug. The '-' sign is a field separator in the
session ID hash. As the username is part of the session ID all scripts
will go bonkers with usernames containing a '-'.
That indeed is worth fixing.
