"properties" -> "open with" - defective statemachine

[Stefan Helmert]

On Ubuntu 16.04.2: The statemachine of the "Open With" dialogue in is defective. To open this dialogue reightclick a file, click "properties" and select "Open With" tab.

The behaviour of the button "Set as default" is correct. After clicking that button, the behaviour of the "Add" button is also correct.

But clicking only the button "Add" after opening the dialogue without click "Set as default", it shows the wrong behavior. Clicking "add" does always the same like clicking "Set as Default". Clicking "Set as default" one time repairs that behavior.

Why that? There are two problems.

Clicking "Add" does have the behaviour like clicking "Set as default" to have one "Default Application" set, if no "Default Application" is set. That is correct.

1st problem: This dialogue starts in state believing no default application is set. But the already set default application is listed as "Default Application". That means, clicking "Add" does the same like "Set as default", when it should not.

2nd related problem: Clicking "Add" to set the "Default Application" the first time, does not set the state that the "Default Application" is set like clicking "Set as default" does. So the 1st problem is repeated.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures.

At a minimum, we need:
1. The specific steps or actions you took that caused you to encounter the problem.
2. The behavior you expected.
3. The behavior you actually encountered (in as much detail as possible).
Thanks!
