[imp] php error on IMP delete function

[Shai at Shaibn.com]

Hi,

>From time to time... when I delete msgs from within reading the msg I get an
error like this:

Notice: Undefined index: 19 in
/usr/share/toaster/htdocs/horde/imp/message.php on line 264

Notice: Undefined offset: 1 in
/usr/share/toaster/htdocs/horde/imp/message.php on line 346

Warning: Cannot modify header information - headers already sent by (output
started at /usr/share/toaster/htdocs/horde/imp/message.php:264) in
/usr/share/toaster/htdocs/horde/imp/message.php on line 475

I'm using version v3.2.1

Why is that?
