           Summary: app refuse to quit and consume ~50% system CPU load
           Product: okular
           Version: unspecified
          Platform: Slackware Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: okular-devel at kde.org
        ReportedBy: chaos.proton at gmail.com


Version:            (using KDE 4.1.3)

way to reproduce:
1, In a terminal, use okular to open a pdf file, say temp.pdf
2, run this script in other terminal:
=============================
#!/bin/bash
i=1
while [ $i -lt 20 ]; do
        mv temp.pdf temp
        sleep 1
        mv temp temp.pdf
        i=$[$i + 1]
done
============================
3, then close the okular window, the main window disappeared. But you can see
okular doesn't quit. The last few messages are:

symptoms：
1, open a system monitor, I can see okular consume nearly 50% "CPU System
Load". When I try to kill it, it does not have any response.

2, When I lsof my system, I can see okular is using my disk.

I wish I have provided enough info that you can debug into it.
