If we're just talking about improving the error message, then can I 
suggest something along the lines of:

 	Patch blah blah corrupted: unable to apply

where the blah blah bit gives the proper filename of the patch.  Then at 
least I can hunt it out and look inside it to see -- aha! my damned proxy 
again.

The current error message says (1) panic panic darcs is broken and (2) 
just identifies the patch by number.  The problem with this is that 
finding the patch file requires a little guesswork and the lucky fact that 
`ls` lists the patches in the same order as darcs was reading them.
