400 Bad Request using OAuth after app restart

[Lutz]

Scenario is client app using OAuth, refresh token to "Bearer XXX", then query this:

http://www.google.com/reader/api/0/stream/contents/user/-/state/com.google/reading-list?xt=user/-/state/com.google/read&r=n&n=50&ck=1341803291

First time around this works fine.

Starting recently, after closing the app, restarting and trying again getting 400 bad request:

    "Cache-Control" = "private, max-age=0";

    "Content-Length" = 76;

    "Content-Type" = "text/html; charset=UTF-8";

    Date = "Mon, 09 Jul 2012 02:34:26 GMT";

    Expires = "Mon, 09 Jul 2012 02:34:26 GMT";

    Server = GSE;

    "X-Content-Type-Options" = nosniff;

    "X-Frame-Options" = SAMEORIGIN;

    "X-Reader-Google-Version" = "553-000";

    "X-XSS-Protection" = "1; mode=block";

"X-Reader-User" is missing

Any ideas what is causing this issue?
