Not off the top of my head, no. I might be able to figure something out
with access to the machine in question (to be able to examine logs and
see command lines and so forth in the source tree, and to be able to
check files elsewhere in the system to run down leads), but certainly
not without, and there'd be no guarantee even then.

This does look like something which one of the developers might be able
to look at and speak on with more authority than I could.
