I have some trouble with sharing documents via Filr using my iPhone. Uploading a file works fine, however when I attempt to share said file I get a red exclamation mark next to the share details, then when I click on the exclamation mark to see the details I get a 'bad request to server' message.

I do not have this problem with the Filr web client on Linux or the Filr client on Mac/Windows.

Is this a known iOS bug or is there something I can do?
