trying the beta 4 win32 installer (Qt4) i can reproduce the bug that
the user describes.
with the local Qt5.2 build the bug is gone.

in general, the code does not have such "logic" to print a page or less.
based on a speculation, here is a patch that disables the vector print
for <Qt5.0 but i don't have the build setup to test it with Qt4.*
after seeing these strange offsets that i had to insert previously to
make the table vector, i really do suspect some QPicture bugs.
