[CentOS] enigmail 0.94.3 on centos-4.6 x86_64 not working

Hi

I have tried to install/setup enigmail 0.94.3  on centos-4.6  x86_64
with no success.
Either thunderbird (1.5.0-12) crashes on startup, or it writes "error in
accessing enigmail service"

I have tried it with a clean thunderbird profile with no success to.

The download and installation works and enigmail is shown as an extension.

gpg is installed and the path is configuerd in enigmail


Has anybody success using enigmail on  centos-4.6 x86_64 ?

regards

Hansjörg
