[Dovecot] panic in mail-index-view.c

With just one user, on a virtual hosting system with several hundred 
users spread across a couple of dozen domains, there is the following 
error, repeated a couple of times a second without variation, when the 
user tries to connect with Thunderbird to read his mail:

dovecot: Panic: IMAP(*******@****.co.uk): file mail-index-view.c: line 
265 (view_lookup_seq_range): assertion failed: (first_uid <= last_uid)

Any help would be appreciated.

TIA,

Peter Risdon.
