If wildcards were allowed in domain transition control directives, calculation
of the domainname to transit to becomes fuzzy. In order to avoid fuzziness,
wildcards are not allowed in domain transition control directives.
You can instead do
aggregator /home/\*/\*\-.xinitrc /user-defined-programs
aggregator /home/\*/\{\*\}/\* /user-defined-programs
initialize_domain /user-defined-programs from any
which the user defined programs will be jumped to
<kernel> /user-defined-programs
domain. You may also want to specify
keep_domain any from <kernel> /user-defined-programs
in order to simplify permissions for user defined programs by (by default)
suppressing domain transitions from user defined programs.

Indeed. This is a bug in ccs-checkpolicy and was copied to tomoyo-checkpolicy.
I've just commited the fix
http://sourceforge.jp/projects/tomoyo/scm/svn/commits/6111
and I will release updated tools packages. Thank you for finding this bug.
