I've found the following backtrace in my .xsession-errors file. It seems
that Emacs is somehow crashing during shutdown. So maybe the problem is
not really about restart, but about some redisplay problem happening
during shutdown.

X protocol error: BadDrawable (invalid Pixmap or Window parameter) on protocol request 62
Serial no: 6422
Failing resource ID (if any): 0x60014c
Minor code: 0
This is a bug!  Please report this to bug-gnu-emacs <at> gnu.org!
