Is it possible to get values of custom fields when fetching a bug using Bugzilla RPC?

If I add custom fields to my bugs in Bugzilla 4+, is it possible to get the values of tehse when fetching the bug using Bugzilla RPC (I use the XML one)? Before I think this was stored in the internals part of the reply, but now I can't seem to find it. I tried including them by adding them to the include_fields in my request, but doesn't seem开发者_开发百科 to help.

I don't understand how I could have missed it before, I even searched the entire page on "custom". Perhaps the text has been updated afterwards. But it now states that all custom fields will be returned when using get on a bug.
