STR:

1. Connect the App Manager to a device
2. From My Device -> Installed Apps, start some app, like say Gallery
3. Click Debug on Gallery to open the toolbox
4. Switch to the Inspector tab
5. Close the toolbox
6. Click Debug again on the same app (Gallery)
7. You will see the Inspector tab is selected, but the actual content of the tool does not appear.  Other tools appear to work fine.

Attachment: Clean up inspector front and actor when reusing connection

The changes I made in bug 912646 to keep the client connected when a remote target closes exposed a few cleanups that were missing in the inspector code path.

Previously, these weren't required since the client would go away when a toolbox is closed, but that's no longer true when you are remote.

Attachment: Clean up inspector front and actor when reusing connection (v2)

An additional change was needed to resolve a race condition.  Currently, when a toolbox is destroyed, the panels, host, and target are all told to destroy and they race each other. 

The complication is that the inspector panel wants to destroy the WalkerFront / WalkerActor and the target now wants to destroy the InspectorFront (which owns the WalkerFront) and the debugger connection (for local tabs only).

In this version, I've made an additional change to delay target destruction until after the panels and host are done being destroyed, in case they rely on an active connection to do their work.

The issue as described in Comment 0 still reproduces on latest Nightly (20131030030201) on Debugger tab.

Using the following STR it can also be seen in the Inspector tab:
1. Open an app
2. Select the Debug button
3. On toolbox select all the tabs and check that they contain data
4. Go to Console tab and close the toolbox
5. Reopen the toolbox and check again the tabs content

AR: The Inspector and Debugger tabs have no content. Please see the screencast: https://docs.google.com/file/d/0BzbDkQ2Zlg86ZklJaDZWZUNoUkk/edit?usp=sharing

Should I file new bugs for these issues? Thanks

Yes. Please. That sounds pretty bad.
