Comment 25 for bug 633292

I can also confirm this bug. Error message :
** (seed:13480): WARNING **: Exception in instance construction. Line 104 in /usr/share/gnome-games/lightsoff/Board.js: TypeError Result of expression 'GLib.main_context_iteration' [undefined] is not a function.

** (seed:13480): WARNING **: Exception in instance construction. Line 194 in /usr/share/gnome-games/lightsoff/Board.js: TypeError Result of expression 'lights[x][y]' [undefined] is not an object.

I've tried Justin Blanchard's workaround which works fine for me, but rather recommend to use a try-catch-construct which will ensure that GLib.main_context_iteration will be executed when there are no problems with it. However Tim Horton announced that he fixed the main_context_iteration issue, so why does it still exist? Any problems with seed?
