Someone (faried) has added an additional Mantis report on this problem, see

The new bug report contains some useful gdb output showing a segfault occuring
in the actual uuid_generate() library call. The VM support code wrapping this
call looks dead simple, so I'm hard pressed to see how that could be wrong.
This plugin is trivial; we must be missing something obvious.

Note, I'm not actually working on this bug, and I've never seen it happen. I'm
just tracking it in Mantis and hoping that someone can point to a solution.
