Useless(?) OAuth error

[malenki]

I keep getting occasionally an error message that OAuth didn't work after my edits were uploaded and the changeset got closed.

Following edits and uploads work fine, too.

What is the point in this?

The cli output starting with creating the changeset:

PUT http://api.openstreetmap.org/api/0.6/changeset/create... OK
POST http://api.openstreetmap.org/api/0.6/changeset/11970277/upload... OK
PUT http://api.openstreetmap.org/api/0.6/changeset/11970277/close... Authorization Required
Error body: Couldn't authenticate you
