Merge #11332: Fix possible crash with invalid nCustomFeeRadio in QSettings (achow101, TheBlueMatt)
cdaf3a1 Fix Qt 0.14.2->0.15.0 segfault if "total at least" is selected (Matt Corallo)
Pull request description:
`QButtonGroup->button()` may return a nullptr.
Accessing the object directly with `setChecked` seems fragile.
This is a simple fix to ensure to never call a button out of bounds (nullptr).
There are probably other places where a sanity check for `QSettings` are required.
Found by @achow101.
Code by @TheBlueMatt.
