From what I can tell the paths are not being formed correctly on this platform. The root part of the path seems to be duplicated e.g.:

D:\art\music\modplug\VSTs\Camomile\Examples\PdStalFx/D:art\music\modplug\VSTs\Camomile\Examples\PdStalFx\hello.pd should actually just be D:\art\music\modplug\VSTs\Camomile\Examples\PdStalFx\hello.pd. Perhaps something about the Wine environment is causing it to use the wrong separators. Let me know if I can provide further information.
