 The GUI fails to start when `g.extension` fails during ''Addons'' toolbox
 creation in `core/toolboxes.py`. GUI should continue just with an empty
 ''Addons'' toolbox.

 After hitting OK, there is no further error or window visible. It does not
 matter what if it is during GRASS start or with `g.gui` with or without
 `-f`, same for 72 branch and trunk.

 This is the error message in a dialog. The `g.extension` error is in the
 command line which is not ideal because it should be at the same place as
 the traceback.

 {{{
 List of addons cannot be obtained because g.extension failed.

 Reason: Process ended with non-zero return code 1. See errors in the
 (error) output.
