These problems shall be fixed now, too.

Here I'm lost. I use something like

  if (NILP (uname) || (strlen (SDATA (uname)) > 0))

uname is a Lisp_Object. SDATA (uname) returns (char *). What kind of
signedness do I break in strlen? Does anybody have an idea?

All this means that dbusbind.c is working and there is no other D-Bus
application running. Too bad ...
