Bug#828106: gnome-sudoku: App generates the same games every time

[Ryan Prichard]

Package: gnome-sudoku
Version: 1:3.14.1-1
Severity: important
Tags: upstream

Dear Maintainer,

When I start GNOME Sudoku and generate a new puzzle, it's always the same
puzzle.  If I generate *another* puzzle, the second puzzles are always the
same.  I assume this isn't the intention.

The problem goes away if I add `srand(time(NULL));` to
`qqwing_generate_puzzle`.  I'm not sure that's the best place for that call,
but the random number generator needs to be initialized somewhere.  Here's the
call in upstream qqwing:

https://github.com/stephenostermiller/qqwing/blob/73027c058d89b8ea517d656c61b43487d75b6ebe/src/cpp/main.cpp#L204

Note that this srand call is in the `main` function, so it's presumably not
relevant to callers of the qqwing library, which is what gnome-sudoku is using.
