I'm still in the process of trying to compile 0.9.8g and 0.9.8k to see if that helps.

I see that F9 is using g... I'll try and use that src.rpm.

FWIW: here's what I see:
A file is encrypted... aes_key::encrypt_block() is called multiple times.
It's unlikely that a file would be exactly a multiple of 16 bytes, so there will
be some left over.

On the last call to aes_key::encrypt_block(), size is less than 16, for some reason
AES_cbc_encrypt() has a seg fault when size is not the block size.

When I change size (3rd arg to AES_cbc_encrypt()) to either 16 or sizeof(data),
I don't get a core dump.
