TLB hangs when using autosensing and toolbar switching

[mls]

Frequent hangs and crashes when using autosensing and toolbar switching.

This is one such reproducible crash on my system (Vista, TLB 5.6.2):

1. In TLB Settings define a new toolbar
2. Create a standalone toolbar for it
2. Right click the new toolbar and define an autosensing workspace pointed to any folder, set a workspace hotkey.
3. Activate the new workspace using the hotkey
4. Right-click the toolbar and Switch Toolbar to any other toolbar.
5. Switch toolbar back to the new one.

If you don't get an error from that, go to the autosensing tab, select the new workspace and click edit. Click finish (with or without making changes). You should get crash when you try to apply the changes using either OK or Apply.
