I changed the above to: "<br>Standard Error: ", as I added:

 echo "this is an error" >&2
 exit 1

to kshark-su-record and the current patch produces:

  ERROR:  Capture process failed: Unknown error
  Standard Error :this is an error

Where I think the below looks better:

  ERROR:  Capture process failed: Unknown error
  Standard Error: this is an error
