to list all special folders. In cmd-getmetadata.c there is a "if" (line 455) who is intended, I think, to avoid the use of wildcards in mailbox name, but at the end the result is an attempt to open a NULL mailbox name who produce the crash. When I remove this condition and recompile dovecot, there are no crashes. It's not clear for me if GETMETADATA "*" is still legal (there is a reference to rfc 5464 in the code) ; but in both cases there is a bug in the code.
