hg convert . . in an svn working copy is likely to convert from svn to svn,
breaking the svn repo at the same time. What you really want is probably:

hg init
hg convert -d hg . .

This works for me

So, you know, don't convert with the SVN working directory as the destination.

We should fix the traceback, but it doesn't seem like a very important problem.

Correct, it will also fail in the same way if the source and  
destination are the same:
hg convert buffet/ buffet/

When pwd is not the SVN working directory, this works correctly.

hg convert ../buffet .

All the ? files is normal.

So it seems all works fine as long as you don't try to convert with . as the
destination?

In the working copy, when I try:
hg convert . .

I get the exact same error(s).  With both commands, if I exclude the  
destination or make the destination a different directory, they will  
both create mercurial repositories with a log.

However when I do an "hg status" on the converted directory, all the  
files are "?" status (not sure if that is a new bug or related)

Have you tried converting a working copy instead?

SVN version 1.4.4 (r25188)

In the working directory, I ran this command.

Simple:buffet Robert$ hg convert file:///usr/local/svn/buffet .
