DOSBox games are calling wine when you open them with double click

[neuromancer]

In the last dev revision (ff9270b), GameHub loads wine when executing some DOSBox games with double click. The compatibility layer is correctly set to DOSBox and the binary is the executable from the game (MS-DOS executable). The log shows that it is trying to execute the executable with wine and then loads DOSBox correctly but using an additional configuration file (?):

It looks like you have wine binfmt installed and for some reason GameHub tries to run game's executable directly instead of using compat tool.

Which platform does this game have in GameHub? Does it use compatibility at all?

[neuromancer]

It's a user-added MSDOS game (interestingly enough, the executable has the +x flag). It uses the DOSBox compatibility mode (and works as expected).

Also, I discovered that my GameHub settings to use double click to run games was disabled. If you enable them, it will not trigger this bug (also it won't trigger #280).
