--- Comment #9 from boris.seve@drillscan.com 2010-06-04 03:44:26 --- I've just tested with rev. g9aa9a12 and the bug is still present.
Both RETURNONLYFSDIRS and BROWSEINCLUDEFILES : Real directories AND files are valid (With wine, files are not valid)
That's the problem. Files should also be valid.
