[imp] Error on message pane

[Frank Pineau]

Most recent (~Oct. 1) stable IMP and Horde from CVS:

Whenever I open a message, the top of the screen reads:

Notice: array_merge(): Argument #2 is not an array in
/<path-to-webmail>/horde/imp/message.php on line 520


Functionality does not appear to be impaired.  Any idea what's causing
that message?
