It's defined in render_handler_agg_style.h and invoked from
render_handler_agg.cpp. The warning happens when
fill_styles[].get_bitmap_info() == NULL which is not rare. It seems
not to be a problem (some movies contain 5-6 fill styles even if
they're never used) but it must be handled to avoid segfaults.

Don't know what's the reason for this and thus the warning message.
