Description

When changing to vector digitizer mode in Map Display and attempting to create a new vector map to start digitizing, it crashes and I get the following in the GUI Console tab:

I use trunk r74162 in a virtualenv with python3.

This is still an issue in r74400 compiled and run in a virtualenv with python3. If trunk is compiled with python2 as usual, it works as expected.

The error points to slightly different lines:

In 74401:

vector digitizer crashes with python 3, see #3777

Just re-compiled and tested. Now, it does not crash, but the dialog to submit each new feature does not appear and cat is not written. v.db.select of new vector digitized is empty.

This is what I get in the GUI console when digitizing polygons:
