Adding Controls to group producing crash

I submitted a report as well...
To produce other weird things add one Value Control then a Slider control....This at times for me totally froze FF where I had to go to the task manager and force FF to quit....It also gave me a File Corrupt error but was to quick to take a shot of....

Edit....Adding a slider then value then slider in that order back and forth a couple of times has produced FF locking up as well...Again with another File Corrupt error....
To make FF freeze I restarted the pc to clear the memory and paging file..When that was finished I double clicked on the Crash Test filter to open FF that way...Then I proceeded with the steps to crash FF...This caused the lock-up....I think the step is to re-start the pc to clear everything....

All right last post on this one.. Lazy Sunday..
Played with this one some more and found that having the Edge Detector in the group was causing the crashing when adding the controls....I took it out of the above and had no issues...So heres the filter again with only the edge detector and an image component connected.......Add the controls as above...
