Something has gone wrong (500)

[Peter.Balazovic]

Binary package hint: ubuntuone-client

Other user of Ubuntu One sent me sharing invitation of his folder at UbuntuOne
By clicking, accept and logging correctly I am getting this answer at Ubuntu One web page
"Something has gone wrong (500)"
Any idea what's going wrong?
Regards
Peter
