Run that again with --traceback and --debug, please.

First thing to know is this has absolutely nothing to do with the above
problem. 'verify' checks the contents of the repository only and doesn't
look at the working directory at all.

The above is saying "at some point you checked in a file called x, and
now that seems to be missing". For every file ever checked in, there's a
file in .hg/store/data/path/to/file.i (and sometimes .d) where that
file's data is stored. And I suspect the corresponding files have gone
missing. 

My suspicion is that you did something silly like "find -name
'.DS_Store' | xargs rm". Oops.

Normally, you could mostly recover by truncating your history back to
the point where the corruption occurred. But these files were all in
revision 0 (the "@0" bit) at the beginning of your history.
