Dolphin uses too much CPU(100%)when right click on video file

1. The CPU usage is 100% . Load in both cores ranges from 95 to 100 percent .
The strangest thing is that ,adding the CPU usage of individual processes
doesn't exceed 50%
2. The hard disk is spinning at maximum speed continuously 
3. At this time, the responsivity is really sluggish. It takes a long time to
appear menu after right clicking, scrolling is really slow, moving windows is
slow(first the mouse moves. after some times, window moves). Nobody can use the
computer at this state
4. This happened when I right clicked on a video file in "DOLPHIN". To
reproduce, right click on a video file, and move mouse over the menu appears .
move mouse over the sub menu of "open with" . This happens in good quality
video files ,not necessarily HD. Surely happens in all HD files(.mkv format) I
tried
.Happened in some non HD files too
5. This happens when an HD is open(tried in VLC,Dragon) too

7. This doesn't happen when file is double clicked in KONQUEROR

8. Another strange thing is that the gnome-system-monitor (shipped with ubuntu)
doesn't show 100%. It shows less than 50% . 

One more thing the compositing was disabled when I tried

Reproducible: Always

Steps to Reproduce:
To
reproduce, right click on a video file, and move mouse over the menu appears .
move mouse over the sub menu of "open with" . This happens in good quality
video files ,not necessarily HD. Surely happens in all HD files(.mkv format) I
tried
.Happened in some non HD files too

Actual Results:  
1. The CPU usage is 100% . Load in both cores ranges from 95 to 100 percent .
The strangest thing is that ,adding the CPU usage of individual processes
doesn't exceed 50%
2. The hard disk is spinning at maximum speed continuously 
3. At this time, the responsivity is really sluggish. It takes a long time to
appear menu after right clicking, scrolling is really slow, moving windows is
slow(first the mouse moves. after some times, window moves). Nobody can use the
computer at this state

Expected Results:  
This much Cpu usage should not be there

Thanks for the report, this issue has been fixed just a few days ago and will be part of the (delayed) KDE SC 4.5.0 version.
