From 7fc8c560e21e7175b1fe33c988f3f30e4b326efe Mon Sep 17 00:00:00 2001 From: David Faure Date: Mon, 29 Dec 2014 16:37:55 +0100 Subject: [PATCH 004/248] Fix QPrinter::setPaperSize regression when using QPrinter::DevicePixel The QPageSize-based refactoring led to casting DevicePixel to a QPageSize::Unit value of 6 (out of bounds). And then the switch in qt_nameForCustomSize would leave the string empty, leading to "QString::arg: Argument missing: , 672" warnings.
