Ahh. I lied. This probably /is/ related to the verify problem. It's 
trying to compare the contents of a file in the working directory with a 
file in the repo and not finding it in the repo. Not a very useful message.

$ hg clone hg hg-break
725 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ cd hg-break
$ touch hg
$ rm .hg/store/data/hg.i
$ hg st
abort: No match found!

With this patch (quite probably mangled as it's the first one I've tried 
sending with Thunderbird):

..we instead get:

$ hg st
abort: No match found for 'e48ab706a921' in data/hg.i!

Have you confirmed that the files mentioned by verify are missing?
