QtCreator based on Qt5.0.2 renders fonts in editor wrong

QtCreator delivered in the complete package from
http://download.qt-project.org/official_releases/qt/5.0/5.0.2/qt-mac-opensource-5.0.2-clang-offline.dmg
renders fronts wrong in editors.

The standalone download from
http://download.qt-project.org/official_releases/qtcreator/2.7/2.7.0/qt-creator-mac-opensource-2.7.0.dmg
based on Qt4.8.4 renders the same font just fine.

Used font here is Source Code Pro

But this happens with other preinstalled fonts, too.
