[qmailadmin] Blanc Quota gives problem

[Alex Curvers]

Leaving the quota blanc (for unlimited) i get some garbelled text in the 
user overview where normally the quota size would be stated. Also its 
not possible to mail this user, his mailbox reached his quota, (while 
its empty)
Is this bug known? or is it just my installation ?
Is there a fix/ workaround ?

Regards Alex Curvers
