Hi J-S,

I tried the program on the machine I have at school (supplied by the school for

segfaults. Here's what gdb tells me :

this=0x0? That doesn't look good. It looks like you're changing the Background before the Viewport has been created. No clue why that would lead to an infinite loop, but that's definitely wrong.
