When starting "geeqie" (an image viewer) I get this in an x2go session on all 3 servers I run. Debian Bullseye (testing), sysV, Windowmaker as wm.
libx2go-config-perl 4.1.0.3-5 libx2go-log-perl 4.1.0.3-5 libx2go-server-db-perl 4.1.0.3-5 libx2go-server-perl 4.1.0.3-5 libx2go-utils-perl 4.1.0.3-5 x2goserver 4.1.0.3-5 x2goserver-common 4.1.0.3-5 x2goserver-x2goagent 4.1.0.3-5
(geeqie:27441): Gdk-ERROR **: 10:09:44.818: The program 'geeqie' received an X Window System error. This probably reflects a bug in the program. The error was 'BadLength (poly request too large or internal Xlib length erro'. (Details: serial 300 error_code 16 request_code 143 (GLX) minor_code 1) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) Trace/breakpoint trap
Is this an x2go issue?

This is probably related to OpenGL. The program uses some OpenGL call of a never OpenGL version than NX supports. Normally the application should check the provided version but this is not the first time that check is not (properly) done.
I suggest to try the x2go libglx workaround as described here: https://wiki.x2go.org/doku.php/wiki:development:glx-xlib-workaround
@Stefan: I think it is time to ship this lib and some wrapper script (as described on the wiki page) with x2go.

Ok, it ends up in an error, I can find out what it is of course, but for the moment I'll use feh instead of geeqie. As it is not a showstopper, I'll wait for the built-in solution. If you want to know what's wrong, it this (I followed the Debian Buster guide and I used mesa-20.2.0-rc2):
[..] Program python3 found: YES (/usr/bin/python3)
../meson.build:867:0: ERROR: <ExternalProgram 'python3' -> ['/usr/bin/python3']> is not a valid python or it is missing setuptools

That would be a better solution :)
