HtmlWindow - "No handler..." when not connected

Hi there

I’m developing an application using wxPython and in particular using HtmlWindow and I’m having a problem with viewing images from the web:

If I have a tag like this and I’m not connected to the web the application shows a warning dialog telling me that “no handler found for image type” (doesn’t specify the type). Obviously I’m not expecting to see the image when there’s no connection, but I expected the same behaviour as using a local file that can’t be found (there’s a little “broken” default image).

Is there a way to make the behaviour similar to the local file case? Is this a know bug?

Thanks in advance,
