I'm getting the following assertion failure with xctool 0.2.7:

-[ActionParserTests testRichMediaExecuteActions] is a C++ Google Test.
With 0.2.6 everything is working fine.

I'd love to share an example reproducing this issue, but the only code that's triggering the assertion failure I found so far is closed source. I'm investigating further, trying to find the commit between 0.2.6 and 0.2.7 that introduced this problem. I just wanted to share this stack trace first, in the hope of that it looks familiar to someone.
