Bug in gpg 1.0.4

Sat Apr 14 17:57:01 CEST 2001

Hi all,

I search the recent lists archives and didn't find this mentioned.  My
apologies if this bug has been detected and corrected.  Encrypting to the
following public key will cause gpg to segfault without fail on my system.
Let me know if you need any more information.  I'm not on the list so please
cc any responses to me personally: keith at claytons.org

Here's gdb output and a backtrace . .

Starting program: /usr/local/bin/gpg -v --encrypt --armor --sign -u keith at claytons.org -r miquel at df.uba.ar testfile
