[Evolution] Problems with filtering email on Evo 2.8.1

[Luis Torgo <ltorgo liacc up pt>]

I've recently upgraded my OS to Ubuntu 6.10. As one of the side effects
I changed from Evo 2.6 (I think...) to Evo 2.8.1.

I had several email filters that were working perfectly. Now, when I try
to run these filters I get a message box saying:

Error while filtering folder.
No provider for protocol 'email'.

I'm kind of stuck on this problem and I would be very grateful for any
hint on how to overcome it. My system is:
$> uname -a
Linux piela 2.6.17-10-generic #2 SMP Fri Oct 13 15:34:39 UTC 2006 x86_64
GNU/Linux

Just out of curiosity I went through the same upgrading process on my
686 laptop, and there I have no problems with the filters... I wonder if
this is an AMD64 architecture-dependent problem...

Thanks for any help.
Luis
