Enigmail stopped working in Thunderbird FC3

[Chris Jones]

I have been experiencing the following error when opening OpenPGP Key
Management sub-menu in Thunderbird.

Error - encryption command failed
/usr/bin/gpg -charset utf8 -batch -no-tty -status-fd 2 -with-fingerprint
-with-colons -list-keys
/usr/bin/gpg: error while loading shared libraries: cannot restore
segment prot after reloc:
Permission denied

Can anyone here tell me what has gone wrong - and more importantly, how
to fix this?
