This also happened in previous versions of My Anime 3. It may be a media portal bug but I can only reproduce the bug with MA3.
If you go back several pages in MA3 to the Media Portal home screen to quickly Media Portal will crash when you try to load MA3 again.
Here are my log files from Media Portal and My Anime 3, I have also included a zip file from Watch Dog (part of media portal) with all the logs from the crash
