That would be the new black proxy window with the "X2GO" branding in dark grey letters, right? It's not a real crash, it just terminates? (I.e., OS X doesn't show an appcrash dialog.)
Yes just terminates.
Maybe taking a look at ~NISuser/.xsession-x2go-errors might show something interesting.
working around it with XFCE and then using the work around for DBUS
when the same user is logged in via ssh and X2go.
So XFCE is working, while MATE is not?
Well kind of had to build in the XFCE work around mentioned in this bug <http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=1083>.
Here's what in the log with XFCE:
