Hello folks,

a user reported this app not working.

Prerequisites: 'winetricks -q dotnet20 jet40'

The app starts fine but when you click an item in the "folder" listbox it crashes with managed backtrace:

The problem happens appears in GdipFillPath() -> SOFTWARE_GdipFillPath() -> GdipFillRegion() SOFTWARE_GdipFillRegion() -> GdipTransformRegion() -> transform_region_element(RegionDataPath) -> GdipTransformMatrixPoints()

"element->elementdata.pathdata.path->pathdata.Count" is zero at that point.

'winetricks gdiplus' prevents the crash and other (non fatal) graphics artifacts (see splash screen for example).
