Metrics type Dialog crashes

The Metrics Type Dialog crashes, if I enter ‘CONTAINS NOT “.”’ in the “custom” field. (3.1.1 (3145))

Probably wrong syntax, but Glyphs should not crash.

Can you reproduce in the latest versions, Glyphs 3.1.2 (stable) or 3.2 (cutting edge)?

That should not crash in the latest 3.2 version (and possible in the 3.1.2 version, too).

In 3.1.2 (3151) and the latest cutting edge still the same (new font file)

Then only in 3.2.

Latest cutting edge is 3.2, isn’t it? Or do you mean future versions?

it shouldn’t have crashed but I put in a few more guards.
