Can not edit long post

[Mugsy]

I created a post that seems to be too long to edit:
​http://mugsysrapsheet.com/2010/10/15/the-list-101-examples-of-why-republicans-should-not-be-allowed-to-regain-control-of-congress/

There was a brief period where I could still edit the post by disabling ALL of my plugins, but after adding more lines, even that trick no longer works. When I click "Edit" from the List of past Posts, or directly via the link on the post itself, all I get is a blank screen (the page is NOT busy like it is trying to load something it can't. I simply get a blank screen.) Nothing else even *tries* to load, and clicking Refresh makes no difference.

I can still edit all other (shorter) posts without a problem, but this one long post is now uneditable (other than "Quick Edit", which allows me to change details, but not the Post text.)

I suspect the Post editor buffer has a limit that I must have exceeded.

Can't reproduce with the text alone - I suspect if anything that this is a duplicate of #8553 (In which case reducing severity since that bug has been around for donkey's years without much traction) Suggest close as dupe.

Definitely sounds like a duplicate of #8553
