Problem identified: It's the BIG-REQUESTS extension. We have disabled that in nx 3.5.99 because it is buggy. Add
X2GO_NXAGENT_DEFAULT_OPTIONS+=" -extension BIG-REQUESTS"
to /etc/x2goagent.options and thunderbird works.
IMHO we never had a working version of BIG-REQUESTS. So it is probably a good idea and I am wondering why it is active in 3.5.0.32 at all.
Forget that. We have BIG-REQUESTS in 3.5.99 and it is working. So disabling BIG-REQUESTS is just a workaround.
As replacing libNX_X11.so with the 3.5.99 version is sufficient to make the error go away I suppose one of the many fixes that came in through updating libNX_X11 to current Xorg upstream libX11 is the solution. But as there are so many it's difficult to identify the right one(s)...
We could try to find the libNX_X11 version where it started to work.
