I couldn't find this directory you're talking about, and couldn't find any
Python example on the internet, sorry. The example in gtk3-demo works fine,
though, but I wasn't able to compile it from the provided source because I
don't know how to C. :/

No, but it now displays the 1st frame, instead of a black screen.

Well, the output was the same every time I ran it. I'll add the log as an
attachment. The *.trace files are big (70-80Mb each), could you tell me what
would be the best way to send it to you?
