[kronolith] Undefined offset

[Dan H]

I am getting this error...

Notice: Undefined offset: 1 in
/home/mail2/mainwebsite_html/horde/kronolith/lib/Kronolith.php on line
1199

I dumped the value of $myemail and it is only the username. No hostname
associated with it.  Did I miss setting a value somewhere in Horde or
what?  This problem existed for me with the alpha release as well as the
head release.

Any ideas?
