I could reproduce this bug in XO 1.5 12.1.0 with git version of Paint

Can be a bug related in any way to different selections?
There are no differences in the fill code between the v42 and git HEAD

Replying to godiard:

I don't think. I tested it several times in XO and sugar-jhbuild. In XO I always had the problem.
I think it's related with some version of a library. We are using:
- numpy / string
- gtk.gdk.Pixbuf
- gtk.gdk.pixbuf_new_from_array / gtk.gdk.pixbuf_new_from_data
- gtk.gdk.COLORSPACE_RGB
- gtk.gdk.RGB_DITHER_NORMAL
I would compare versions of those libs.

Tested again with the correct version of the Git Repository. Same results.

numpy:
- jhbuild: 1.5.1
- XO 1.5 12.1.0: 1.6.1
After upgrading the "numpy" version in my jhbuild to "1.6.1" I can reproduce the error on my jhbuild instance.
So, it's a library version problem. numpy 1.6.1 has a bug.
Here is the function that uses numpy:
What should we do in this case?

Replying to humitos:
- cat ~/.sugar/default/logs/org.laptop.Oficina-6.log
---- RuntimeError: could not create GdkPixmap object
This error happens when you click with the "selection" tool and release the button without moving the mouse. But it isn't related with the invert colors issue

There are two ways to do the inversion: using string and using numpy. The "string" version works properly. Maybe we can just comment the numpy version if we are going to release a new version of sugar in the following days.

It works for me in jhbuild with git version of Paint.
