Switching to selection mode causes crash.
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
If there is not an active render module and you switch to selection mode the application crashes.
To reproduce: Connect to built in server. Split view vertically. Delete selected view. Switch to selection mode.
Other applications may not have an active render module all of the time. The selection manager should be able to handle NULL as the active render module.
