Summary: Applying a change in Configuration for a table-based view pops 2 error dialogs for each selected column checkbox.
My tests were on Windows 10 with 6.0.1 version. And it needs to be tested on other OSes.
Before starting Gramps, rename your gramps/gramps60 folder (and for any other Gramps version you have in your Gramps User Directory). You want to start with a clean slate to avoid any old gramps.ini imports, view .ini files, or other carryover from a previous version.
Start Gramps 6.0.1
create a new tree and load it
Switch to the Notes category (all categories with a configurable view are affected)
notice the columns that are visible.
View Configure
count the columns that are selected
Select another column
Click the Apply button
2 error dialogs are generated for each checkbox that was originally selected:
14176872: ERROR: grampsapp.py: line 188: Unhandled exception
Traceback (most recent call last):
File "C:\Program Files\GrampsAIO64-6.0.1\gramps\gui\filters\_searchbar.py", line 139, in search_changed
type = self.search_model.get_value(node, 3)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: Argument 1 does not allow None as a value
(Testing against 6.0.0 would be good too. The Apply error dialogs do not exhibit in 6.0.0 on Windows.)
Don’t forget to restore your old Gramps User Directory folders
