Hello,

ZynAddSubFX 3.0.3 in standalone version and also as a VST2 plugin opened in
LMMS in wine can't find any preset. File browser widget (File-> Load instrument
for eg) opens empty control without the possibility of select any folder.

Everything works fine on Windows 10.

Steps to reproduce:

1. Download

2. Extract folder
3. Run zynaddsubfx.exe

See attached screenshots.
