gnome shell logout/crash

[doniks]

Recently it is happening a lot that gnome shell suddenly logs me out.

I've just checked and saw some errors in syslog, e.g.:

Nov 26 19:39:28 hp gnome-shell[11142]: St:ERROR:../src/st/st-bin.c:206:st_bin_destroy: assertion failed: (priv->child == NULL)

I have the feeling it is related to mounting stuff. E.g., I am now avoiding to use sshfs, because i have the impression that this makes it more likely. just now (for the 19:39 line above) I tried logging in with a Nexus 7 tablet plugged in which I guess would also result in some mounting/filesystem action. However, as I am typing this, I am logged in and the tablet is still connected, so, maybe it's unrelated
