It was a bug indeed. The crash occured actually in a different place than
the assertion - a NULL pointer was being passed to sprintf (). It turns
out that most getpwuid () calls in MC are checked for != NULL and proper
action is taken, except this one.
I'm tracking down another problem now - related to the ftpfs feature. Once
I got it fixed I'll release an update.
