I just upgraded from darcs-2.4.4 to darcs-2.5.0 on my Mac OS 10.6
system, and when I tried to pull two patches it seemed to hang after
asking the first question. After waiting a few minutes, I hit C-c and
then tried again and then it worked normally. Here is the transcript of
what just happened:

WARNING: Doing a one-time conversion of pristine format.
This may take a while. The new format is backwards-compatible.

OK, so we don't know enough about this bug to do anything about it 
(since we can't reproduce it).

I think we're waiting for more information about how to reproduce this.

If we don't hear back about by say January, we should probably mark this 
given-up
