png images not shown in windows

[nzjrs]

See mailing list

I came around a strange problem trying to add an image to a Map object.
When calling add_image I get the following error.

GtkWarning: gdk_drawable_real_draw_pixbuf: assertion `src_y >= 0 &&
src_y + height <= gdk_pixbuf_get_height (pixbuf)' failed
gtk.main()

I'm using the precompiled builds available at the website ( btw, can you
please fix the error on the link for the windows version of 0.7.3 ? ) or
actually the link that is provided in John's blog for 0.7.2 . The same
happens when trying to run some of your examples where add_image is
called..

No such errors using the linux version ( tested from source and packages
for 0.7.3 ).

Any ideas ?

I used the all-in-one bundle offered at
http://ftp.gnome.org/pub/GNOME/binaries/win32/pygtk/2.22/ . So GTK+ is
2.22.x .

Your answer got me to check some more, the problem is more specific,
only occurs with .png format. jpeg images are rendered without any problem.
