Please let us get this fixed with the version of x2gobroker you find
in the nightly builds.
It is very likely, that you will encounter the same issue when using
x2gobroker from the X2Go nightly builds, but that version should be
the one to use for testing setups, as it will be release soon.
And before the release, we should get your problem solved.
Thanks+Greets,
Mike
