[kronolith] offset 1 patch..

[Chris Bowlby]

Hi All, 

 Each time I've done an update to Kronolith, I seem to get a re-curring
offset 1 error, this is the error:

Notice: Undefined offset: 1 in
/usr/local/www/horde/kronolith/lib/Kronolith.php on line 1002

I found that the issue is due to not checking for a length > 0 on a
string before the explode takes place (which is what is spitting out the
error), here's a patch to fix it.
