Been seeing these occasionally for the last few weeks. Only way to fix is to remove cache files in the affected mailbox. Reproduced with both 1.2.5 and 1.2.6.

If not: there is patch: imap: Don't crash on SELECT .. QRESYNC if it didn't give seq-uid map. http://hg.dovecot.org/dovecot-1.2/rev/352eab3d6ade Hope that helps Regards, Pascal -- The trapper recommends today: f007ba11.0928222 at localdomain.org

Rebuilt with the latest 1.2.7-pre code yesterday, and I am still seeing this (on at least 2 different mailboxes in the last day): Oct 20 13:23:32 bigworm dovecot: IMAP(slusarz): Panic: file imap-fetch.c: line 2 27 (get_expunges_fallback): assertion failed: (mail->uid > next_uid) Oct 20 13:23:32 bigworm dovecot: IMAP(slusarz): Raw backtrace: imap [0x4a199b] -> imap [0x4a1a13] -> imap [0x4a10f6] -> imap(imap_fetch_begin+0x6bb) [0x42415b]-> imap(cmd_select_full+0x54a) [0x41e5ba] -> imap [0x420b4d] -> imap [0x420c2d] -> imap(client_handle_input+0x135) [0x420e55] -> imap(client_input+0x5c) [0x4219 2c] -> imap(io_loop_handler_run+0xbd) [0x4a988d] -> imap(io_loop_run+0x18) [0x4a 8d08] -> imap(main+0x531) [0x429441] -> /lib/libc.so.6(__libc_start_main+0xfd) [ 0x7f6c456599ed] -> imap [0x4199f9] Is this an issue with needing to delete cache files from before the fix? Or is this still an issue? michael
