vlQt4_test is crashing on assert

[Fojtik]

I suspect, that a main problem is using argv[1] without checking argc. "test_battery.run(test, argv[1], format);"

This would fix a problem: test_battery.run(test, (argc>=2)?argv[1]:"Empty", format);

You are passing std::string through constant reference. And even NULL in argv[1] is not acceptable.
