hello, could you please diagnose the regression in file picker, for some reason it can not find the repo - I think it was caused by the import of latest YUI 2.8.0r4, looks like they introduced some regressions
I have already found one problem in async connection request caused by missing check if callback submitted

steps to reproduce:
1/ open some page with editor
2/ click add image
3/ select upload repository
4/ circle keeps spinning, firebug shows error "repo is undefined"
