Bug 137313

Hi, I am writing for a bug i noticed recently in konqueror. I work with postscript files and I often need to preview them. And there is the problem. When  I single click the file (*.ps) , I get an error  report from KDE crash Handler. The strange thing is that postscript and ghostscript packages are installed. Also  what suprises me is that when I just place the mouse pointer over the file everything seems ok including the small preview , information about the file , size , date , etc.... If there could be any solution or advice on solving this problem I would be grateful , since I always need to preview my postscript files before modifing  or printing them. Here is the report from the KDE Handler:
Using host libthread_db library "/lib/tls/libthread_db.so.1".
`system-supplied DSO at 0xffffe000' has disappeared; keeping its symbols.
[Thread debugging using libthread_db enabled]
