794885 - Decoding app_info object fails with "TypeError: expected string or buffer"

Status: RESOLVED FIXED

(Testing Graveyard :: Mozmill, defect)

Running Mozmill on Windows gives me the following failure right after the initial start. Looks like we are failing in decoding the appinfo object now. Looks like a regression from my patch on bug 793764. :/

Traceback (most recent call last):
  File "z:\data\code\mozmill\mozmill\mozmill\__init__.py", line 751, in run
    mozmill.run(tests, self.options.restart)

    frame = self.run_test_file(frame or self.start_runner(),

Fixed by backing out the patch on bug 793764. I will take care of the issue on that bug before re-pushing.
