Additional note: if a pair exists, moving the kerning slider doesn't crash Inkscape.

I have been using Inkscape 4.8.2 and the similar bug is happening. I am using a mac OSX 10.8.5 and xcode 11 XQuartz 2.7.5 (xorg-server 1.14.4).

1. Open Inkscape
2. Open the SVG Font Editor (Text>SVG Font Editor).
3. Using font already set up (also happens with a new font)
4. Select previous font (or new font)
5. In the Kerning tab, move the Kerning value slider - able to align two fonts together
6. Once back into Glyphs tab type in letters which have just been paired.
7. Crash.

An error message box appears - however I cannot see any words, application freezes.

Also once the font has been created - should the kerning / pairing stay together?
