Explicitely choosing a subkey leads to breakdown of gpg 1.4.0a for windows

Sun Dec 19 22:11:30 CET 2004

Hi!

I tried gpg 1.4.0a for Windows on a german Windows95-Installation.

First I generated a testkey.
While playing around with it, I wanted to explicitely use older, but
valid subkeys. (As normally gpg uses the newest ones, even if they
have a lower bit number.)

gpg -r EF711C2A! -e FILE

Then gpg broke down and the system gave me the following error
message:

######

The key is attached (and not send to any keyserver).
I tried to use its primary key for signing instead of the newer
signing subkey and it worked. I generated another key and there
signing and encrypting to older subkey worked.
I booted Windows again. (Standard procedure..)
But the described breakdown was reproducible everytime.

So it seems to be a problem that comes especially with this key and
encrypting to older subkeys. (Standard use of this key is completely
normal.)

I hope my information helps you.

PS: The key is attached, but here is an overview:
