EUREKA, I just managed to get the Sharing Violation in a controlled fashion.
With Brainstorm open, I typed a query into my Answer Bar, an on screen pop-out bar from Answers.com. I noticed, the error occurred while using this tool, at least 5 out of 8 times.
With further testing, I can reproducibly get this error with the Answer bar open, with or without text typed inside the bar. The error occurred 8 out of 8 times (I stopped counting) every 60 seconds (timed): 60 seconds after I close the Violation warning, another pops up, even as I type this note on a second monitor.
Trying to pin it down further, it apparently only occurs, at least within my patience span, when the file which had the original violation, is open in Brainstorm. I can send this file to you.
