[gthumb-list] segmentation error when running gthumb through ssh

[Paolo Benvenuto <paolobenve gmail com>]

I'm trying to run gthumb on another ubuntu xenial pc. Usually it worked like a charm.

Now (3.4.3) I get:

$ ssh -XC otherpc

$ gthumb 

libGL error: No matching fbConfigs or visuals found

libGL error: failed to load driver: swrast

libGL error: No matching fbConfigs or visuals found

libGL error: failed to load driver: swrast

libGL error: No matching fbConfigs or visuals found

libGL error: failed to load driver: swrast

** (gthumb:1428): CRITICAL **: Failed to parse arguments: Unable to initialize the Clutter backend

segmentation error

Any hint?
