Glyphs keeps Quiting

Every time I try to do some work in Glyphs it keeps closing after a few minutes, even if I am not actually working in it at the time. This is the error details I get when the report window pops up:

You need to get the latest version. The problem is fixed the. Please re-download from the website.
