        * providers/imap/camel-imap-folder.c (get_matching): Set *set to
        NULL if we dont get any matches.
        (imap_sync_online): If we get no matches, skip any work, also
        reorder some code to make it easier to skip.  See #31031.

        * providers/imap/camel-imap-store.c
        (imap_check_folder_still_extant): Default to "TRUE", if the list
        command failed, it probably means a server problem, assume the
        worst.  This makes imap_refresh_info not clear the exception and
        crash.  Fixes crash of #31000.

        * providers/imap/camel-imap-folder.c (imap_refresh_info): Make
        sure we pass the exception to imap_folder_selected(), otherwise
        failures can be lost.  See bug #31000.

2002-10-01  Not Zed  <NotZed@Ximian.com>

        * camel-folder.c (thaw): Add an assertion that the frozen count>0.
        (freeze): Same for >= 0.

        * camel-vee-folder.c (camel_vee_folder_remove_folder): Use the
        unmatched freeze_count when thawing folders removed from
        unmatched, rather than the folder's freeze_count.  Might be
        related to #27391.
