thanks

The problem is the following implementation in
/usr/include/x86_64-linux-gnu/qt5/QtTest/qtestcase.h:
# define QFINDTESTDATA(basepath)\
    QTest::qFindTestData(basepath, __FILE__, __LINE__)

With the patched gcc in the unstable reproducible builds setting
__FILE__ to something other value, this does no longer find the
test data.

I do not really see any reason for blaming the users here for using
a documented public Qt API for accesssing test data in the source
directory:
  http://doc.qt.io/qt-5/qtest.html#QFINDTESTDATA

I've added reproducible-builds at lists.alioth.debian.org to Cc for giving 
input what a reproducible and portable implementation might be for Qt.
