  I have an hypothesis concerning the issue, and why we have a hard time reproducing it ourselves.
  
  I had to add a wait in the test to make it predictable, which I am not proud of :
  
  line 490 in kfilewidgettest.cpp
  
    // once we drop a file the dirlister scans the dir
    // wait a bit to the dirlister time to finish
    QTest::qWait(100);
  
  So this may work well on fast systems like my owns with SSD but on CI with less resources this might not be long enough.
  Either we can extend a bit this wait and hope for the best or maybe if you see a way to actually get an IO signal when the dirlister is done.
