I tested this bug last night on Kubuntu 13.10 using Wine 1.7.11 and the latest Radeon driver. I launched Rainbow Six Vegas 2 using Steam. It took about 5 minutes from double clicking the game in Steam to the Ubisoft intro video to appear, but other than the unreasonably long load time, the game ran flawlessly (albeit quite slow during fire fights probably due to the Radeon driver)
I have not experienced any error messages while launching or playing Rainbow Six Vegas 2.
For me, the game launches right away. Seems to behave itself fairly well. Wine 1.7.1 and Wine 1.7.10.
