The game throws an error message after starting:

This is a regression from Wine 1.5.21:

Reverting the patch on current git (wine-1.7.0-223-g8f09d34) or native msvcrt
works around the problem.

Steps to reproduce the problem:
1. download and install uqm-0.7.0-1-installer.exe
2. in the component selection window uncheck the "3DO Content" option, so only
the core game will be downloaded (~12 MB).
3. start the game with uqm.exe
