[Planetlab-devel] key convert error?

[Barış Metin]

Hi Josh,

Looks like a bug in the version of M2Crypto you have. I could
reproduce it on Fedora 8. The package on Fedora 12 doesn't have the
issue.

I have prepared a quick fix as a workaround (see below). I guess we'll
need to depend on a newer version of M2Crypto.
