[Kdenlive-devel] [PATCH 13/16] projectsettings.cpp: return if open() fails

[Mikko Rapeli]

Fixes Coverity CID 709281: Unchecked return value (CHECKED_RETURN)
Calling function "QFile::open(QFlags<QIODevice::OpenModeFlag>)" without checking return value (as is done elsewhere 45 out of 47 times).
No check of the return value of "xmlf.open(QIODevice::OpenMode(_ZN9QIODevice9WriteOnlyE))".
552    xmlf.open(QIODevice::WriteOnly);
