Error when opening an image

[CsatiZoltan]

The lastest version of ImagePy on Linux throws the following error when I open any image:

(__main__.py:330): Gdk-CRITICAL **: 11:41:03.714: IA__gdk_drawable_get_depth: assertion 'GDK_IS_DRAWABLE (drawable)' failed

(__main__.py:330): Gtk-CRITICAL **: 11:41:03.714: IA__gtk_paint_layout: assertion 'style->depth == gdk_drawable_get_depth (window)' failed
show img

AttributeError: 'Canvas' object has no attribute 'set_handler'

I went into debugging mode and self.canvas really doesn't have a set_handler method.

I close this issue. The sure solution is to install it to a new environment with conda. Then it works.
