I am getting this error when trying to run B2G mochitests:

This could conceivably have something to do with the B2G mochitest on mozbase refactor.  We don't run B2G mochitests on the desktop build on TBPL, so breakage would be easy.

I'm not saying it's impossible, but I don't think the profile change is the cause. I did black box testing with both the old and new way of profile management and ran diffs on the files in the generated profile.

I can reproduce this locally on linux.  When the tests start, I see an error on the desktop screen:

"Firefox can't find the file at app://unknown/nothing.html"

Additionally in the log I see:

!! got no appInfo for test-container.gaiamobile.org

Comment 4

[Jonathan Griffin (:jgriffin)]

The app://unknown/nothing.html string comes from:

http://mxr.mozilla.org/mozilla-central/source/netwerk/protocol/app/AppProtocolHandler.js#96

It looks like we are not able to successfully launch the test-container app.

Comment 5

[Jonathan Griffin (:jgriffin)]

I backed out http://hg.mozilla.org/mozilla-central/rev/947b9aa5e2d3 locally, and the problem disappeared.  I'll look into it more tomorrow.

Comment 6

[Jonathan Griffin (:jgriffin)]

The problem is that with the above changeset, we no longer copy the gaia profile, so we can't launch any gaia app (like the test-container app).

Verified that things are working happily again.
