[TxMt] "scriptmate.rb:128:in `initialize': Permission denied" when running Python script

[Daryl Spitzer]

When I invoke "Run Script (PyMate)" from the Python bundle, I get:

/Applications/TextMate/TextMate.app/Contents/SharedSupport/Support/lib/scriptmate.rb:128:in
`initialize': Permission denied -
/Users/darylspitzer/Programming/Altera/Perforce/miscellany/infrastructure/integration/integration_status.py
(Errno::EACCES) from
/Applications/TextMate/TextMate.app/Contents/SharedSupport/Support/lib/scriptmate.rb:128:in
`open' from /Applications/TextMate/TextMate.app/Contents/SharedSupport/Support/lib/scriptmate.rb:128:in
`initialize' from
/Applications/TextMate/TextMate.app/Contents/SharedSupport/Bundles/Python.tmbundle/Support/PyMate/pymate.rb:24:in
`new' from /Applications/TextMate/TextMate.app/Contents/SharedSupport/Bundles/Python.tmbundle/Support/PyMate/pymate.rb:24

This started happening yesterday, and then went away.  Now it's back.
How do I make it go away for good?

I'm running 1.5.6 (1405).
