URI file upload is not working anymore

Hi !
I used to upload source release of my packages from the sf.net hosts directly to OBS with the > Add File-save_file from URI- form, about 6 weeks ago.
now that I want to make an update with a newer source package (.tar.gz URI), I get this error :

NoMethodError: undefined method `size' for nil:NilClass 

you see, because I’m running a not too very fast broadband upload stream, I need to use the URI upload to avoid double uploading my files…
thanks for any help

This was caused by a rails update of the webclient, and should be working again now.
