software-center crashed with DocNotFoundError in __init__(): Document 345 not found

This crash occurred on an Oneiric system installed from the netboot installer earlier this week, just upgraded today to take all updates. I ran Ubuntu Software Center, clicked on Installed Software | Provided By Ubuntu on the left, clicked "Show 1296 technical items", started scrolling, and then got this crash.

I'm not sure if Software Center itself crashed (maybe it just relaunched very quickly, and kept state) -- the window is still there.

This is with software-center 4.11.
