Sometime in the last few weeks, FlickrExport stopped working.  When I attempted to upload photos to flickr from digikam, the FlickrExport plugin indicated that my token expired and that I needed a new token.  Hitting the ok button to obtain one, I received a popup error with the following message:

Error occured: Unknown Error. Cannot procede any further.

I've done some googling about and found that it sounds like flickr has recently updated its auth api, which I expect is involved in this issue (as several services I use with Flickr no longer can be authorized properly).  If you could please look into this though, I would appreciate it.  Thanks!
