The title says it all, really : when I try to use the Shift-I Style Inspector on a 'say' textbox accessed through rollback, the inspector crashes. I tested it on many a line of my project and it systematically failed*, so I guess either I broke the system by simply typing text

or there's a problem - and, as far as I can decipher the traceback, I'd lean toward the latter.
As far as I can tell, this is low-priority, but could be nefarious and/or bothering for those wanting to customize rollback behavior.
* Can having failures when you expect failures be counted as a success

?
