Can't get the BASIC:ACL engine to work

Hello,

I've setup the following in my burpui.cfg file (using v0.60-dev):

[Global]
acl = basic

[BASIC]
user = somepasswordhash

[BASIC:ACL]
user = '["serv*"]'
#user = {"MyAgent": ["serv*"]}'

Whenever I use the '*' wildcard, I can connect but won't see the client with account 'user'. Tried both syntaxes. If I happen to remove the wildcard and use the complete client names, it works.

Best regards.
