Crash at start after closing game and reopening.

I was playing, then some keymaps become irresponsive. I closed the game, intending to reopen and getting them responsive again. When trying to reopen, the game crashes, with this freeorion.log:

Deleting config.xml solved the problem. I'm attaching the config.xml file that caused the crash.

Diffing that with the default config.xml and incrementally editing it, shows me that the problem is on line 59, which reads like this in the faulty file:

Code: Select all

<exit>MOD_KEY_LCTRL | MOD_KEY_RCTRL | MOD_KEY_LALT | MOD_KEY_RALT+GGK_RETURN</exit>

I didn't manually edit the file that caused the problem, that was auto-generated when I changed the keymap, via options screen, for exiting to desktop to Ctrl-Alt-Return, which, BTW, worked as expected.

I added a try-catch block to stop the crash, but it still doesn't properly interpret a hotkey option string with 3 or more modkeys specified. Don't have time at the moment to look into it in detail.

Cpeosphoros, can you open an issue on github? So we don't forget it...
