We are running Windows 7 using VmWare Virtual Desktop (VDI). So, my x2go client runs on that Windows desktop. The crash is actually happening in vcxsrv.ex and I was able to obtain the following additional information:
(1) The VDI admins updated some VDI runtimes on our VDI desktop instances to VMWare version 6 around the time we started to experience this crash
(2) Here is a more detailed dump of some debug information I found:
