[imp] Group Lists in Address Book

[Joseph Malone]

When one of our users tries to send mail to certain groups he's  
created in the address book, he gets an error.  This is what gets  
logged:

hordeCVS.log:Jan 12 09:15:37 HORDE [error] [imp] Group name did not  
validate. [o                                              n line 560  
of "/srv/www/htdocs/horde/imp/lib/Compose.php"]

Any ideas what causes this problem?  Could it be illegal characters in  
the group name, or a group name being to long?
