Added SRU information for review.

** Description changed:

+ [Impact]
+ 
+  * Currently, this is the number one bug affecting Ardour users of
+ Ubuntu (including Ubuntu Studio) per the Ardour team.
+ 
+ [Test Case]
+ 
+  * Install Ardour in Ubuntu (or simply install Ubuntu Studio on a system)
+  * Attempt to launch Ardour.
+  * Test will fail if there is a crash without explanation or apport bug alert. Please note that failure does not occur on all systems.
+ 
+  * Workaround: uninstall csladspa
+ 
+ [Regression Potential]
+ 
+  * None.
+ 
+ [Other Info]
+ 
+  * Per the Ardour team, this is currently their number one bug report. Only workaround is to remove csladspa which isn't ideal for Ubuntu Studio users expecting the distro to work "out of the box."
+  * Working with the Ardour team keeps (and/or reestablishes) Ubuntu (and therefore Ubuntu Studio) as a recommended distro for audio production and use of their product. This bug is currently an hindrance to that effort.

+ Original bug:

  After installing the Cadence program from KXStudio, Ardour presented
  this crash.
