Hi, in IE6、7、8 chinese version roundcube can't open pdf as attachment, it says loading data... and doesn't open the file in the frame. firefox works ok! ( that can prompt me to save attached file in IE6.0 englisth version,but still says loading data.. in the frame. )

if filename in Chinese (maybe is not English is same) the above is occurred,in englisth filename , it's ok and prompt me to download or save the pdf file.
