That worked fine, thanks.  Still don't know what this thing does (the 
things dependent on it seemed either irrelevant or mysterious), but I'm 
happy to resolve the issue this way.

Interesting, thanks again.

This might not be an issue due to the explanation from Warren below.

The user has been around longer than FreeBSD has existed and the UID is 
used across various system with different OSs, so the reinstall was 
actually the simpler solution.

Out of curiosity, I tested this theory and it's correct.

Are there any files out there that messagebus is expected to own that I 
should double-check after the reinstallation?

Thanks to everyone for all the good advice.
