Yep, exactly the same issue. Our dirty workaround is to ssh -X back into the same host and it will work.

The error was something along the lines of "Can't forward a local display" (sorry, didn't save the exact error and I have since reverted back to using the spank plugin). With X2Go (and some other remote desktop solutions) you are assigned a local display number, which apparently causes this problem to surface.
