Crash on auto-fill with hyphenated name

[mediapathic]

I'm having a crashing bug which I am having trouble narrowing down.

If I type [[ to search for a note, I can sometimes get a crash on completion.

If I link to [[201806011606-SymbolicMechanisms]] it crashes consistently.
If I change that same note to [[201806011606 SymbolicMechanisms]] (note lack of hyphen), no crash.
If I link to [[201901091435-notefortesting]] it crashes consistently.
However! If I link to [[201901091435-note for testing]] it does not, (and links as [[201901091435-note]], which makes sense.)
