setting "default privileges" only allows to choose "public"

Hi,

I just upgraded to pgadmin3 1.16.0.

If I try to set some default privilges via "right click on schema -> 
Properties -> Default Priviliges" I only get to choose from public but no 
other groups are listed.

It does work in 1.14.3 though.

I have been trying it with postgres-9.1 and 9.2 with equal results.

Any hints on how to fix that? Should I file a big report?

Cheers,

Thomas
