The crash is likely caused by imap_urlauth_fetch_parsed() returning 0 without having set *mpurl_r to NULL, and then imap_urlauth_fetch_local() freeing an uninitialized pointer.

Right, fixed: http://hg.dovecot.org/dovecot-2.2/rev/24aa10efe132

I also noticed another crash: http://hg.dovecot.org/dovecot-2.2/rev/2a3134b0c25d
