Third time: Undefined offset wrror/warning.

[M Z Rahman]

Okay this the third time I got this error message while deleting messages after
reading them. I posted about this before also, but got no answer. Hopefully,
someone will kindly take his time to answer now.

-------------the error message-------------
Warning: Undefined offset: 1 in /www2/horde/imp/message.php on line 248

Warning: Cannot add header information - headers already sent by (output started
at /www2/horde/imp/message.php:248) in /www2/horde/imp/message.php on line 369

------error message end here--------------

After this message shows I have to manually enter the URL http://myurl/horde/imp
to go back to the INBOX. Back button of the browser also doesn't work.
