Hello Niko,

I have forwarded this upstream
<http://article.gmane.org/gmane.comp.encryption.gpg.libgcrypt.devel/4487>
and got a quick response, whichcan be summed up in short with:
1. encryption without setkey must not be used.
2. gcrypt should throw an error instead of a segfault

Please take a look at the short thread on libgcrypt-devel for full
details.
