[Enigmail] Enigmail problem

[Mike]

Hello,

I am running Linux ( Debian lenny/sid ) and when I try to sign my email
( OpenPGP ),
I get Enigmime service not available error.  I am running for email
Icedove 2.0.0.6 and browser Iceweasel 2.0.0.8.

I installed Iceweasel, Icedove and Enigmail all from the deb repositories.

Any ideas on how to resolve?

Thank you.

Mike
