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

[Nicolas Ecarnot]

Hello,

User since long of x2go, I'm now facing the following issue :

- client host is XUbuntu 19.10, with a 4.1.2.1-2 client
- server host is XUbuntu 19.10, with a 4.1.0.3-4 server

Everything sounds good and I can do basically anything I want (things 
are responsive, colours are OK, aso...)

But when running the images viewer "GThumb", the software is not 
launching and stops with the following error :



double free or corruption (!prev)
Abandon (core dumped)


Obviously, I made my homeworks and search around for clues. Though I 
find many similar cases with people having the same issue, it doesn't 
seem specifically related to x2go not gthumb.

BUT...

Yet I send this message here because my target server is also a 
workstation I use everyday *not remotely* and on which I can perfectly 
run gthumb.

Should I look at some colour depth settings, at missing libraries, or 
could anyone lead me to some precise x2go settings I could tweak?

Thank you.
