hi, i'm using f10. i've been facing a strange problem. while reading a specific pdf file with any reader- okular or document viewer and in any desktop- kde or gnome, it suddenly crashes i.e. the application suddenly closes reporting a bug. This is not the case while reading any pdf file but with only some files. maybe they are corrupted but that should not be so as they are working just fine in windows.
Also i notice that when i take my mouse pointer to such a file, the dolphin browser hangs for some seconds.

I don't have a damn clue about this stuff. Has anybody got it?? Plz help..
