[X2Go-User] Cannot launch GThumb (double free or corruption)

[Nicolas Ecarnot]

Hallo Uli,

Danke for your answer.
I read the StackOverflow thread, but either it is beyond my 
understanding, either I don't get if I can bypass some checks by setting 
some parameters.
I tried to set some, according to what I read in the thread, but that 
doesn't change anything.

Maybe you have an additional hint?

Nicolas
