Hey Mikes :-)
Thanks for your replies. We resolved the problem by recommending the x2go client version 4.0.2.1 to our users which includes a sufficiently old Vcxsrv. We are fine with this solution. Please keep this upstream-bug in vcxsrv in mind for the case more applications show the problem and replicated bug reports are created.
Thanks for your efforts on the x2go-software! Martin

Some updates on this bug:
I've tested several VcXsrv-Versions from http://code.x2go.org/releases/binary-win32/3rd-party/vcxsrv-modified-b y-x2go-project/ The bug purely occurs with the more recent versions of VcXsrv - like 1.15.2.0 and 1.15.2.1 The bug does NOT occur with the older versions 1.14 (tested 1.14.3.2).
So the bug is caused by changes made in VcXsrv from version 1.14 to 1.15. I used the debug version "vcxsrv-debug.1.15.2.1-xp+vc2013+x2go1.installer.exe" to receive the following trace of the SIGFAULT:

Hi Martin,
This is a bug that I do intend to fix when I get a chance, even if it means fixing the bug in the VcXsrv code. However, I am not an expert at C, and I probably will not fix this anytime soon. (Patches from others are welcome.)
However, in the meantime, you can follow this workaround:
- Install VcXsrv (VcXsrv-xp) 1.14.3.2 and remember where you installed it.
- Configure X2Go Client for Windows to use that vcxsrv.exe as an external X server: Options -> Settings -> X-Server settings
If you have a large number of users or machines that need these settings, you can save the settings a registry key that can be exported and imported per-user-account and per-machine. The reg key is: [HKEY_CURRENT_USER\Software\Obviously Nice\x2goclient\settings]
