Description Milan Krivda 2008-02-08 10:54:57 UTC 
Version:           4.0.0 and 4.0.1 (using KDE 4.0.0)
Installed from:    Gentoo Packages
Compiler:          gcc-4.1.2 qt-4.3.3
OS:                Linux

In KDE 4.0.0 and 4.0.1 most times when i open dialogs, parent application and dialog stop responding for 10 - 20 seconds, after then application normally respond and i can work again. This bug is nicely repeatable by opening Dolphin and trying to delete some folders. Same lockups sometimes occur by working in konsole and using auto-completition feature.

After some testing it seems that KDE sound handling is responsive for this bug (i think KDE is waiting for response from sound server). I dont use and dont have installed arts. After redefining soud player to play, error dont occur more.
Comment 2 Matthias Kretz 2008-04-29 17:49:01 UTC 
does the lock happen once, and not again until you restart the application? or does it happen every time you open a file dialog?
Comment 3 Milan Krivda 2008-04-29 17:58:25 UTC 
I cannot try it, because i switched to ubuntu now. What i remember it was first time and not more until application restart.
Comment 4 Matthias Kretz 2008-04-29 18:22:41 UTC 
Ok, then I guess you're seeing the effect of the phonon backend getting loaded on demand. It is programmed to load the backend when a preview for an audio or video file should be done. I see that effect only on mouse-over of a media file. And then it's like 1 second (and your hardware looks more capable than mine). Are you really seeing a 10-20 seconds lockup?
Comment 5 Milan Krivda 2008-04-29 18:36:14 UTC 
Yes 10 - 20 seconds.
Comment 6 Dario Andres 2008-12-28 01:05:28 UTC 
Have you experienced this bug again with a recent KDE version? (4.1.3 / 4.2beta2 / 4.2svn) ?  Thanks :)
Comment 7 Milan Krivda 2008-12-28 11:49:42 UTC 
No. I used more distros from time when i reported that problem and i dont seen that bug newer more (KDE 4.1.x, 4.2 beta 1).
