//List of assumptions made whose correctness is not guaranteed by GTK+:
//The character '9' is as wide as the widest of '0' '1' '2' '3' '4' '5' '6' '7' '8' '9'.
// Failure leads to: The BPS delta creation progress window being a little too small.
// Fixable: Not hard, but unlikely to be worth it.
//g_spawn_async does not write to argv or its pointed-to strings.
// Failure leads to: Corrupting the configuration.
// Fixable: Not hard, but unlikely to be worth it.
