[1.5.2] Crash when I am changing the language to Polish

[Mateix]

I changed language to Polish (Edit / Preferences / User Interface / Language / Polski) and I received a message:

"Internal error - log written to c:/Users/user/Desktop/wings_crash.dump Click a mouse button to continue working".

Then Wings 3D stopped working.

Specs of my PC:

- Intel Core i7 4770K
- MSI GTX 760 2GB
- 16GB RAM DDR3

Driver version of my graphic card: 335.23
The problem does not occur in earlier versions of Wings 3D
