RuntimeError: wrapped C/C++ object of type QComboBox has been deleted #332

Closed andrew-demerchant closed 3 years ago

I'm seeing the following quite often (though not 100% of the time) when I create a new blank database. It does seem to create the database, though, but I'm unsure if it's a fully working one or not:

`An error has occurred while executing Python code:

Thanks for reporting the bug!

I managed to reproduce it by opening Midvatten settings dialog (the dock widget with the DB tab), closing it again and then creating a database.

It should be fixed now in branch qgis3_henrik. The settings dialog didn't close properly (it was still referenced from midvatten after the user pressed the X) so some objects were alive while others, like the QComboBox, was destroyed.

There is no issue with the database itself. This error happened after database creation. Just make sure it's selected in the DB tab in Midvatten settings dialog like it should be.
