The following is a mail conversation I had with Christian (working on the importer/exporter for Collada in Maya)
… that I thought I should post here since it can be very helpful for others.
Thank you for your interest. I suggest that you post this on the
public Collada forum, since it would be of interest to others too.

I'm only testing on Maya 6.0.1 and 6.5. If you have 6.0, I strongly
recommend you upgrade to 6.0.1, it’s a free upgrade anyway.

Not implemented yet, but it's in the plan.

No one else has reported that problem. There’s probably something strange
happening with your plug-in path. Check your Maya.env, verify that there is
no duplicate of COLLADA.mll left around. I’m sorry, but I just don’t have
the time to provide end-user support on this plug-in.

Yes, this was an actual bug. Thanks for reporting it. It will be fixed in
the next release.

Good luck on your side. If you still can’t get the plug-in to load properly
in the Maya UI, I would suggest posting on the public Collada forum. Maybe
others have had a similar problem and will have the time to help you. Sorry
I can’t be more helpful,
