How To Repeat

when submitting a key with:

$ gpg --keyserver-options=verbose --keyserver mailto:pgp-public-keys@keys.pgp.net --send-key colliera@nu.ac.za

the following error is logged on the terminal:

Use of uninitialized value in concatenation (.) or string at /usr/local/libexec/gnupg/gpgkeys_mailto line 199, <STDIN> line 37.

this appears to be due to the fact that variable $key is not initialised. an extract from the perl debug output:

(/usr/local/libexec/gnupg/gpgkeys_mailto:178) match
Guessing start of match, REx ^KEY (\w+) BEGIN$' against KEY colliera@nu.ac.za

Match failed

=>  SV_NO

this appears to indicate that the regular expression fails to match (sorry, don't know much about perl myself!).

Fix

After some consideration, I've fixed this by changing the regexp in
gpgkeys_mailto. This is the smallest change possible on the stable
branch.
