When your phone is a guinine Nokia , so not a Chinese lookalike , you could try the following , since there is probably a corrupted file somewhere in the device , try to locate :
1) remove the memorycard and try again : when this gives the same result : the corruption is in the device .
2) in this case the best is to consider a Vulcan Death Grip or a Hard Reset . See my post here : http://www.allaboutsymbian.com/forum//forum/thread/81021/ or http://my-symbian.com/s60/faq/showquestion.php?faq=4&fldAuto=29
