Crash when zooming with grid on

[bernard decock]

I installed version 0.12 on Ubuntu8.10.

I can zoom in/out an image (by means of the sliders) without any problem. If you do the same thing when you put the grid on, then Xnview crashes with a floating point-exception. Hereby the last output-lines.

Anyhow. A nice program!
