Crash when typing too fast

[ByteHamster]

Mostly happens when typing nonsense, but should probably still be investigated because it makes users lose the text they already entered.

Good spot! Thanks for bringing that up! I did miss to parse an upstream libqalculate color that is used by the internal formatter to indicate "undefined". Thats why it probably only occurred when typing nonsense, but now it should be fixed.

Actually, typing undefined into the input bar crashed the app deterministically, which is now fixed in the main branch.
