[RCU] MDB2 Error message in 0.3rc

Hello,

I've been running 0.3rc for a few weeks and, since this morning only , I have the following message on the top-left corner of the window:

DB Error in /<XXXX>/program/include/rcube_mdb2.php (623): MDB2 Error: constraint violation Query: _doQuery: [Error message: Could not execute statement] [Last executed query: EXECUTE mdb2_statement_mysql_586751139f2cf6ff93d7883f2080104b31458319d USING @0, @1, @2, @3, @4, @5, @6, @7, @8, @9, @10] [Native code: 1062] [Native message: Duplicate entry '1-INBOX.msg-108742' for key 2]

It doesn't appear at every reload, it's quite random...

Any idea of were this could be coming from ?

Thanks, Julien
