We need a stack to do anything here.  Something is calling this API too late or too early.

In the debug log I see:

Or are you looking for a minidump?

That's not a useful stack ... we need symbols here

Comment 4

[Andrew Halberstadt [:ahal]]

Reading the log, the problem seems to be that the harness isn't catching the timeout before the mozharness timeout is triggered (which doesn't check for minidumps). Looks like someone already filed bug 889317 for this.
