odd message - execmod related

[Genes MailLists]

  I was trying to test the early version of thunbderbird 3.3 and got the
following :

-------------------
SELinux is preventing
/opt/Local/vers/mozilla/released/thunderbird-3.3a1pre-100930/thunderbird-bin
"execmod" access to
/opt/Local/vers/mozilla/released/thunderbird-3.3a1pre-100930/libxul.so.
-------------------
SELinux denied access requested by
/opt/Local/vers/mozilla/released/thunderbird-3.3a1pre-100930/thunderbird-bin.

/opt/Local/vers/mozilla/released/thunderbird-3.3a1pre-100930/thunderbird-bin
default SELinux type is usr_t, but its current type is usr_t. Changing
this file back to the default type, may fix your problem. If you believe
this is a bug, please file a bug report against this package. Allowing
AccessYou can restore the default system context to this file by
executing the restorecon command. resto
-----------------------------------

 (1) Note the message: "default SELinux type is usr_t, but its current
type is usr_t."

confuses me ... ?


setebool -P execmod 1

allowed it run - but that seems like way overkill.

 (2)  What is the 'right' way to allow
/opt/Local/vers/mozilla/released/thunderbird-3.3a1pre-100930/libxul.so
to be execmod'ed (or whatever its called) ?

 Thanks
