At work at the moment, will fix later today. Sorry for the inconvenience.

I let watch dog generate a crash report (normally I auto kill it before it gets to that point) in case it is really from a conflict.

Oops, that should fix it. Will upload to curse once travis finished the build.
Could you retest with that please? Edit: Builds are also available here, uploaded directly by travis.

Your change did fix it.
