This is interesting. So setting MALLOC_CHECK_=0 does not change
anything? (have you checked that you included the _ at the end of the
variable name?).

X2go is using nxagent. nxagent is an Xserver. It is - feature-wise -
not on par with the current (local) X server you are probably using
(or maybe you are using wayland locally?). So maybe gthumb is not
correctly checking if the X server feature set is the one it expects.

What version of nxagent are you using?

Am I right that your X2go connection is not dying?

Can you run xdpyinfo inside your session and post the output regarding
extensions? Can you also please post your server-side
/etc/x2go/x2goagent.options?
