Critical errors

[2V3EvG4LMJFdRe]

Nicotine+ version: 3.1.0.dev1
Operating System/Distribution: macOS High Sierra

Describe the bug

These errors appear on a window as "critical error", the first when I open Nicotine+, the other when I try to close it.

Expected behavior

No error windows to appear.

Steps to reproduce the bug

Close my previous instance, of a previous build. Open the newly compiled build, and try to close it.

Additional context

Could have to do with settings not getting properly carried over?
