Well, removing -f will work. I had committed this to trunk (develop) branch 
when an IRC conversation revealed that this is a bug. See

https://bugreports.qt-project.org/browse/QTBUG-33749

for the open bug report. Maybe voting might help.

Yes, I skipped the merge to 1.55.0. I have not followed the bug and don't have 
the time to fix this myself at the moment.

Yours,

Jürgen
