Grepmail caching problem with mbox extension

[Kenneth Pronovici <kenneth.pronovici@cedar-solutions.com>]

After upgrading one of my boxes to Debian etch (pre-release), I began
having problems with the mbox extension.  The error looked like this:

   Error executing backup: Error [9] executing grepmail on [/home/me/mail/folder].

I pulled the following command-line out of the debug log:

   grepmail -a -u -d 'since 2007-04-02T00:31:22' /home/me/mail/folder

Running that command by hand yielded this error:

   Use of uninitialized value in subtraction (-) at /usr/share/perl5/Mail/Mbox/MessageParser/Cache.pm line 84.
   Use of uninitialized value in numeric ne (!=) at /usr/share/perl5/Mail/Mbox/MessageParser/Cache.pm line 83.
   Use of uninitialized value in subtraction (-) at /usr/share/perl5/Mail/Mbox/MessageParser/Cache.pm line 108.
   Use of uninitialized value in numeric ne (!=) at /usr/share/perl5/Mail/Mbox/MessageParser/Cache.pm line 107.
   Cache data not validated. This should not occur. Please notify david@coppit.org at /usr/share/perl5/Mail/Mbox/MessageParser/Cache.pm line 113. 

Oddly enough, this error occurred only for the root (the user running
cback), not for the user that owned the file.

The ultimate fix was to remove root's grepmail cache file, which was
apparently corrupted:

   # rm ~/.grepmail-cache

That solved the problem.
