Nah the HTTP stuff is unrelated, it just happens to be the last proper thing which is explicitly logged there (checking to see if there's news from the server about game version).
Looking at the data, the actual crash could maybe be something to do with the audio system trying to be unmuted when the app regains focus, which normally isn't an issue for most startups, but if yours is taking especially long, then perhaps that could be a problem??? This is something you might be able to test, actually. One method would be to start it up and make sure to not leave the app/wine/whatever to use OS or some other software, just wait, but perhaps a more user-friendly method to start with is to, as long as you already have a user/advanced.cfg file in there, change the "muteAudioOnFocusLoss" setting to 0 before starting up. See if that helps! (if it does work in that case then this might have actually discovered a bug I never knew about...)
