I seem to have the same problem, running r55795 of libs & e.
Besides on e restart/exit, it also happens when rotating the screen with
xrandr. Attached are two gdb backtraces.

I don't think it's caused by the places module, as I don't have it
loaded. The problem seems to be in e_gadcon.c, there the id_del func is
called with an invalid parameter (gcc->cf->id is invalid, because
gcc->cf is NULL, see the bottom of my backtraces).

Than it's very recent... looks like this bug is caused(/exposed?)
by r55771[1] where a 'gcc->cf = NULL' is added.
