Chris, I reverted your change in DescriptionScannerInfoProvider back to 1.11 as it makes the test fail.

I did not notice this reversion till now.  The bugzilla description didn't indicate the problem.

The code does need to change because blindly running toOSString() on every discovered path totally messes things up for remote projects.

I plan on reverting the fix but I'll have a look at the tests to make sure they continue to pass.

I will file a separate bugzilla for the issue the original fix was meant to address.
