Hi Abel,
Thanks for sending this.
I've uninstalled the rc-1 version and installed rc-2.
I can't say why, but from a really quick test PK is not (yet!) crashing. I have uploaded a photo to Flickr and to dropbox successfully.
I haven't had a chance to desteg them yet, but certainly so far its working.
I haven't installed/uninstalled anything (apart for rc-1) since I tested it before, so I can't say what went wrong.
I'll test it more thoroughly this weekend.
Thanks again,
Bernard
