Comment 5 for bug 120872

I fixed this in the upstream SVN repository in r59 with the following patch:

diff --git a/src/MainSDL_Event.cpp b/src/MainSDL_Event.cpp
index 5ab76ba..ba87463 100644
--- a/src/MainSDL_Event.cpp
+++ b/src/MainSDL_Event.cpp

 // resetMouseMotion();

      case SDLK_p:
+ grabMouse(game->game_pause);
    game->game_pause = !game->game_pause;
    game->audio->pauseGameMusic(game->game_pause);
    break;

Chromium BSU needs upstream developers, so see my mail on the Debian games list if you are interested.
