Infinite error tabs when custodians is greater than quorum and quorum is 1

[m4gpi]

Steps to reproduce

• Open Patchbay
• Open /dark-crystal
• Set quorum to 1
• Select 2 custodians
• Complete the rest of form
• Hit Perform Ritual

Expected Behaviour

It raises an neat custom error in the dropdown error box.

Actual Behaviour

Dark Crystal goes blank. Patchbay opens a new blank tab, which when you click on it (or /dark-crystal tab), infinitely opens another new one.

See terminal error:

Error: Threshold number of shares must be an integer between 2 and 2^bits-1 (255), inclusive.

Also followed by these two when clicking on the error tabs - these aren't Dark Crystal specific, are related to how Patchbay handles errors:
