This fixes the wrong problem, i'm afraid - if you do this, then the file is not opened as a template, but rather just as a file (which results in unexpected behaviour, when you are not attempting to edit the template itself). It also doesn't fix a related issue for new file creation. Basically, this is caused by switching to the QtQuick 2 components (the old components had an implementation for this functionality, which i am currently porting over). Thank you for spotting it, though :)
