[imp] Global whitelist spamassassin accidental deletion via imp.

[gimili]

I have a long list for global whitelist in spamassassin stored in mysql 
(entered via horde).  All works perfectly.  I paste a long list into 
whitelist in horde then save.  One day they all disappear.  When I am in 
imp and whitelist one more email address it erases all of the global 
whitelists for my user name as they are already global and it would be 
duplication.  This makes sense but now when I click the "Make Settings 
Global" and hit save not only is the list gone for my user name they are 
also deleted for global.  Now I get nasty calls saying why are important 
people ending up in junk folder.  I googled for this problem and 
searched bugs but did not find anything.  Perhaps I am doing something 
wrong?  Thank you.
