Comment 13 Orion Poplawski 2015-12-15 18:43:10 UTC 
Hmm, I can't reproduce.  What desktop environment?  Does it happen every time?  If so, can you collect valgrind output?

dnf install valgrind
valgrind /usr/bin/x2godesktopsharing
Comment 14 Davide Repetto 2015-12-17 15:26:40 UTC 
In the meantime the customer did a dnf upgrade and this problem apparently went away.

Here is the valgring output, but I think it is now useless:
