The backtrace is below, but as soon as I saw it, I realized what the problem is.

I had a library loaded (for the curious, geben) that advises open-network-stream.  The package seems to have been abandoned, and also causes problems with erc.

Removing it removed the problem starting slime.

Sorry for the noise,
Chris.
