[rt-users] Can't call method "HasMemberRecursively" on an undefined value when promoting user to privileged

[Nathaniel Griswold]

Hi,

I'm running an rt-3.8.0 instance (upgraded from rt-3.4.4). I have a
problem with granting unprivileged users rights.

When i try to "Let this user be granted rights" in the "Access
Control" panel of the user modification page i get the following error
in my browser:
---
Can't call method "HasMemberRecursively" on an undefined value at
<rtpath>/bin/../lib/RT/CachedGroupMember_Overlay.pm line 221,  line
1662.
---

And the end of my apache error_log looks like this:
---

Does anyone have any ideas as to what might be causing this? I've
searched around but no one else seems to have had the problem. The
same thing happened when i tested it in rt-3.8.1rc5. I've not yet
tried rt-3.8.1

Thanks
