TclError: unfinalized data stream in PNG data

seems to be on your side, not related to the bug

I. e. there's a problem with my program?

According to the devs — yes.

It's a project of berkeley... How could I try to debug this? I'm a newbie in python programming...

It seems that somewhere in that project there is a creation of image from raw data (e.g., "image create ... -data {iVB...").

This data is actually an image, likely encoded with base64. It seems that the data was obtained using old png library and can't be handled by the new one. As a possible solution, you can find the original image, transform it to base64 and put the new value for the '-data' option. Or you can just use '-file' instead of '-data' to load image from file.
