I've seen this problem happen twice for the same bug. I don't think that 
the person who is "removing" the QA contact has the permissions needed 
to remove the contact.
I tried adding back the contact once, but was not allowed to readd the 
contact.
Are there any bugs filed against bugzilla for this problem?
