Emulator

What's the problem?
When in an application, pressing home, then selecting wii menu (with the wii menu installed)
dolphin reports "Unknown pointer to 0xffffffff" then crashes if you select yes.

Dolphin version with the problem (as it appears in the title bar, Ex.: "R
4779" or "R 6403M"):

I've only seen this problem in r6665, I haven't tested a newer or older revisions.
(optional) Dolphin version that does not have the problem:

Operating system and version:
32-bit or 64-bit:

This is on Mac OSX 10.6.3 64bit,
Game ID (as it appears in game properties, Ex.: "GZ2P01" or "RSBE01"):

I've tested Epic Mickey, Mii channel and new super mario brothers.
Build command-line (not on Windows):

Was the ISO a plain dump from disc, compressed and/or scrubbed?
