It looks like make_executable is being called on a file that either
doesn't exist, or that you don't have permission to open.

The error handling in make_executable has been changed in 0.22 as part
of a fix for a race condition.  Previously, the error was being
propagated back to the caller; now we throw an exception.

Two things to try:
- look at the contents of .mt-attrs and compare to the files that exist
  in your working copy or...
- strace monotone to find out which file it's failing to open.

We shouldn't be able to end up in a situation where the .mt-attrs file
has records in it for files that don't exist in that revision...
perhaps there is not enough sanity checking being done on the .mt-attrs
file.
