[Pkg-lxde-maintainers] Bug#801319: x2go + gnumeric

[Lutz Fischer]

Dear Maintainer,

After a reboot the shmget error disapeared - but it still crashes with:

(lxpanel:1017): GLib-ERROR **: 
/build/glib2.0-BMd9vh/glib2.0-2.46.0/./glib/gmem.c:100: failed to 
allocate 18446744039349813252 bytes

the crucial combination seems to be x2go-client and gnumeric.

Reproducible via starting a x2go session and starting gnumeric within 
the x2go-session

I did start lxpanel with valgrind:
valgrind lxpanel --profile LXDE

Disabling the taskbar-plugin "solves" the problem.

seems like there is some trouble with the icon...
