Yes, but:
- on Linux, that statement does nothing AFAIK (drkonqi continues to work just fine for me)
- on OS X, its only effect is that the executable is built as a traditional POSIX executable instead of as an "app bundle". There is no difference in functionality (IOW, app bundles make it easier to provide features that are irrelevant to drkonqi).

I can either drop this issue, or I can make the statement conditional (`if(APPLE) ...`). But note that in most if not all previous RRs I was told that there was no need to make this statement conditional.

Those are the easy and straightforward ones fixed by this patch.

Both Apple's clang "6.0.0" and gcc 5.3 (on Linux) refused statements like `QWeakPointer<QFileDialog> dlg = new QFileDialog(parent,defname);` . My initial attempt was to follow the documentation for QWeakPointer, and do `QWeakPointer<QFileDialog> dlg = QSharedPointer<QFileDialog>(new QFileDialog(parent,defname));` but that caused a crash as soon as I clicked on the "save backtrace as" button - on both platforms.

In the end I tested using QFileDialog (and `QFileDialog::selectedUrls()` as kate5 does, and that works (on OS X; haven't had the chance to test on Linux yet).

Is that actually a possibility, and why wouldn't it be in Kate? Are there no other ways to prevent it, or check for its occurrence?
