Glyphs Mini crashes after applying Offset Paths filter

Glyphs Mini crashes frequently after I applied the Offset Paths filter to the glyphs and afterwards used the scissors tool to remove some of the line segments. In this order; Draw glyph, apply offset path, cut line segments with scissors; export, CRASH!

I tried but I cannot reproduce it in 1.5.7 (49) on 10.12.1. can you send me the .glyphs file to support (at) (this website without www)?

What version of Glyphs Mini do you have and can you send a screencast of what exactly what you do? Sometime there is a little thing different.
And did you send crash reports?
