I still do not think this belongs here. It is too easy to add a new way to show
the manage dialog without adding this line as well. The only reason for the not
re-updating yak shave was to avoid the infinite loop. Please find a way to fix
the infinite loop.

Done! There's no infinite loop anymore, so I'm now suspicious it was either a)
entirely unrelated in ToT or b) I had written some nonsensical code before
coffee that made no sense. :( 

Super sorry for this!
