Code review comment for lp:~j-corwin/openlp/presentations

I pushed some more incomplete changes after my original merge request, since I was expecting the "merge" to only merge the revision I'd requested and not later ones on the same branch.
However it seems this is not the case, and my later incomplete changes ended up merged in trunk.

This appears to have broken things on Linux. I do apologise, and I will attempt to sort out the mess tonight if no-one beats me to it!
