Not without knowing the root reason of why you are seeing that
behaviour. The patch comes from upstream, so there are at least two
possibilities:
1) the patch is wrong.
2) the code you run uses the bug fixed in that patch as a feature.
In other words: how can we know the bug is in qtcore or on your app?
Of course if you can find why the patch is wrong I'll be happy to
revert it.
