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.
