Comment 3 for bug 910382

Enigmail seems not to recognize the gpg executable. The auto-detection of GPG files, and using "override" with a specified path to /usr/bin/gpg has not effect. Using the "Wizard" dialog for browsing to the gpg executable fails to consider the selected path /usr/bin/gpg as the executable. Running /usr/bin/gpg from terminal works fine.

confirmed also when running from ppa:
running enigmail Version: 2:1.3.4-0ubuntu0.10.04.1~mtn1
running thunderbird Version: 10.0~b1+build1-0ubuntu0.11.10.1~mtn1

The following configuration works fine:
Thunderbird Version: 8.0+build1-0ubuntu0.11.10.1
enigmail Version: 2:1.3.2-0ubuntu1.3
