I would prefer to add an "Insert page" item to the Edit menu.

This one doesn't seem easy to be fixed. setColorCount() is used to set
the number of color entries in the color map of an image. I guess Qt
4.5 the number is hard coded to be 256. We set it to 256 anyway. Would
you please add an #ifdef around it to skip it in 4.5? Please send a
patch if it works. Ah please do test with a PDF file that contains an
image to really check if it works.

Hehe... I know kubuntu 10.4 is much more interesting, but we really
appreciate a developer with a native Qt 4.5 environment to test things
out...
