cabal test = permission denied?

[Guy]

I can successfully run cabal test, and my test suite passes. Cabal's output it:

Running 1 test suites...
Test suite tests: RUNNING...
Test suite tests: PASS
Test suite logged to: dist\test\foo-0.1-tests.log
cabal: permission denied

foo-0.1-tests.log is present and correct. There is also an empty file cabal-test-4513.log.

I am on Windows 7 x64, cabal 1.10.1.0. Running as Admin makes no difference.
