Executables compiled with a 5.5 installed through the offline installer cannot run because they do not find the platform plugin:

QFactoryLoader::QFactoryLoader() checking directory path "/home/kakoehne/Qt5.5.0/5.5/gcc_64/platforms" ...
QFactoryLoader::QFactoryLoader() checking directory path "/home/kakoehne/dev/tmp/build-widgetsapp-Desktop_Qt_5_5_0_GCC_64bit-Debug/platforms" ...
This application failed to start because it could not find or load the Qt platform plugin "xcb".

Indeed the path returned from QLibraryInfo::location seems corrupted:

qDebug() << QLibraryInfo::location(QLibraryInfo::PluginsPath);

returns

"/home/kakoehne/Qt5.5.0/5.5/gcc_64\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000/plugins"
