Fix InspectionTool crashes due to bad perspective string errros

To ensure backward compatibility from version 4.2.3* to 4.2.2,
use the config key 'perspective1' for version 4.2.3 and later.

LoadPerspective => LoadPaneInfo raises an Exception, not a wx.PyAssertionError.
Therefore, change it to catch only Exception.
