Hello. This is just a FYI mail to get the problem (and solution) into a searchable archive.. I ran into the following problem with mbox: Panic: IMAP(XXX): file index-sync.c: line 39 (index_mailbox_set_recent_uid): assertion failed: (seq_range_exists(&ibox->recent_flags, uid)) Which was fully reproducable in 1.1.3, but in the newly released 1.1.4 this does not happen anymore. All is well, birds are singing etc. /Tomas -- Tomas ?gren, stric at cs.umu.se, http://www.cs.umu.se/~stric/ `- Student and SysAdmin at Computing Science, University of Ume?
