Comment 0 for bug 1880803

For any version newer than 19.04, follow the steps below and then upgrade. It will display the same errors when trying to copy or translate the view with the old layout.

On 19.04

to replicate:
- go to User menu-> Preferences -> Settigns
- set 'Show controls to add and remove columns when editing a page' to yes and save
- create a view
- set a custom layout e.g. 3 rows with 3 columns and 1 row with 1 column
- play with the column changing the widths
- display the page and make a copy

the following errors are displayed
