Found it, apparently dovecot-1.1 does not like a NULL parameter to the
array_get function anymore:

-        execvp(*(char **)array_idx(&command, 0), array_get(&command, 
NULL));
+        execvp(*(char **)array_idx(&command, 0), array_idx(&command, 0));

With this additional change, the attached full patch manages to update
the XEXEC plugin to dovecot-1.1. This was tested with the 'average'
example and that worked flawlessly.

Regards,

Stephan
