登錄後不出現facebook移動共享對話框

我遇到了一個問題，我試圖根據用戶提供的一些輸入信息將用戶發送到移動共享對話框。這適用於桌面瀏覽器和我試過的Android瀏覽器。但是，如果用戶尚未登錄，它將在iPhone 3G上失敗。用戶會被提示登錄，但登錄後他們在Facebook上面臨空白屏幕 - 基本上是死路一條。登錄後不出現facebook移動共享對話框

這裏是我試圖把它們發送到（由隱藏客戶端信息編輯）的網址：

http://m.facebook.com/dialog/feed?app_id=123456789&display=touch&link=http%3a%2f%2fwww.someotherdomain.com%2fdir%2fsubdir%2f12345&picture=http%3a%2f%2fwww.someotherdomain.com%2fImages%2fdir%2fsubdir%2f12345678.jpg&name=Some+Name&caption=Some+Caption+-+Its+Location&description=Title%20Of%20Event%2c+now+playing+at+Some+Location.&redirect_uri=http%3a%2f%2fsomedomain.com%3a54251%2fcheckin%2fthanks%2ffacebook%2fsuccess%2f

這裏是登錄屏幕上的URL時，它會出現在iPhone：

我錯過了什麼？也許我沒有正確地編碼參數中的URL？ This question sounds similar，但是這着重於授權應用程序，我不希望這樣 - 我只是想讓用戶分享一些東西。謝謝！
