We discovered an issue with tst_qxmlstream on VxWorks in COIN, caused by a timeout in the COIN scripts.
After adjusting this timeout, we started seeing issues with tst_qfiledialog, which now takes too long.

This is "too long" run:

tst_qfiledialog ..................   Passed  1036.07 sec

This is "correct" run:

tst_qfiledialog ..................   Passed  262.97 sec

when running manually on VM we see that test freezes after

11:49:23 Totals: 56 passed, 0 failed, 5 skipped, 8 blacklisted, 353520ms
11:49:23 ********* Finished testing of tst_QFiledialog *********

results are not deterministic
