[Enigmail] keyserver list lost with latest Nightly on TB 3.0

[Marco Zehe]

Hi there!

I just installed Enigmail and GnuPG on Vista, Thunderbird 3.0a1 today.

The first time I tried to look up a public key, I saw a list of 4
servers in the Key Management/Keyserver/Search.... dialog. After it
didn't find the key on the first server, I returned to the dialog and
selected a different one.
After it didn't find it on that server, either, I returned, and found
that all items were gone. I now have 4 items labelled "Undefined".

How do I get the servers back? Where is that data stored?

Thanks,
Marco
