Well, the crash is due to a bug in unexpunge.c, line 507 should read:
   syslog(LOG_WARNING, "unable to open/lock mailbox %s", argv[optind -1]);

(I reported this to the cyrus bugs email address a while ago).

However, if this is fixed then you will just get told
'unable to open/lock mailbox user.foo.subfolder'. I have virtdomains enabled
and use:

unexpunge -l fiddaman.net\!user.xxx.mailing_lists.cyrus

for example, which works fine. Not sure what you do for the default domain or
with virtdomains disabled, maybe try '\!user.foo.subfolder' ?

HTH.
