My guess is that this is an instance of

 https://tests.reproducible-builds.org/debian/issues/unstable/ftbfs_due_to_f-file-prefix-map_issue.html

  An example of failure related to this are programs that expect
  __FILE__ to expand to some absolute path, but instead finding themselves
  a relative one.

as QFINDTESTDATA() uses __FILE__:

 https://sources.debian.org/src/qtbase-opensource-src/5.14.2+dfsg-4/src/testlib/qtestcase.h/?hl=215#L216

   #ifdef QT_TESTCASE_BUILDDIR
   # define QFINDTESTDATA(basepath)\
       QTest::qFindTestData(basepath, __FILE__, __LINE__, QT_TESTCASE_BUILDDIR)
   #else
   # define QFINDTESTDATA(basepath)\
       QTest::qFindTestData(basepath, __FILE__, __LINE__)
   #endif
