Comment 5 for bug 696410

First of all I didn't know that Flash movies can directly be opened by browser like: File | Open. Nice. I have watch your video and now I can reproduce problem.

1. Paste some picture to Pinta 0.5 on Windows XP sp3
2. Effects | Artistics | Oil Painting
3. Just decrease Coarsenes settings by one (or any other number).

I have tried several things increasing and decreasing Coarsenes settings and if I understand correctly Pinta always crashes when settings gets bellow 50 Pinta.

No error is returned. I have also tried to execute from cmd and there is also no error.

I have also tried to reproduce the problem in Pinta 0.5 on Ubuntu 10.10 and Pinta. On Ubuntu Pinta does not crashes if getting bellow 50, but it does crashes if it gets to 0, then the error is returned (in terminal):
