I have no idea.  If I remember
correctly, I started Emacs and told it
to load the org-agenda files, and that
would be it, these are plain text.

I do every day at least once.  This did
not happen before.  I tried to reproduce
in an Emacs optimized for debugging, but
the problem did not occur.

(gdb) p $rs
$7 = void

Upps, "rs" != "rsp"

(gdb) p $rsp
$10 = (void *) 0x7fffffff95f8

Ciao; Gregor
