Probably this is the IDEA algorithm.  To check this use the option
"--status-fd 2"   which will print a warning line in this case.

An OpenPGP compatible implemenation should never use this algorithm if
it is not listed in your preferences.  However if you created that
public key with PGP 5 (with IDEA support) and imported it to GnuPG
this may happen.  A way to change the preferences is to change
expiration time of your key - this way, new preferences are attached
to your key.

I will enhanced the output to print the id of the unknown cipher
algorithm.
