Version: (using KDE 4.2.1)
Installed from: SuSE RPMs
Malformed -- contains character which is displayed as uknown character "?".
Such file can be opened and viewed by any tool -- MC, more, you name it -- it is listed by Konqueror, open dialog, dir, etc. Yet after opening the file (i.e. try to open) okular just displays message error that it cannot open such file.
After removing such characters it is possible to open the file.

I am not sure my report is a duplicate:
* I _can_ open files from file->open for utf-8 filenames
* I _cannot_ open files from file->open for malformed filenames, i.e. filename that contain "?" characters (I believe this means it is not legal character).
Of course I can tell for sure after KDE4.2.2 release.
