Description ycs wyw 2009-10-13 19:59:39 UTC 
Version:            (using KDE 4.3.2)
OS:                Linux
Installed from:    Ubuntu Packages

Hi,

I'm on Kubuntu 9.04 with KDE 4.3.2 updates (from "http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu" repository), and I'm having very slow logins after the "Folder View Widget" was added on Desktop, with the location: "Show Desktop folder" (that contains 5 subfolders with about 30 Gb of data):

The "folder view widget" is rendered quite fast on login, but it "freezes" the desktop about 90 seconds (i.e: "kickoff menu" doesn't work, nor I can't launch applications from taskbar). 

It seems the "Folder View Widget" is trying to read the "Desktop" folder files... because the disk has heavy I/O activity during login... but I also tried to disable "show previews" in "icon settings" from "Folder View settings > Display" options without success.

Curiously, when I change location property from "Desktop" to "Home" directory (with the same Desktop folder + 4 Gb additional data), or when I remove the "folder view widget", the login only takes 22 seconds. 


This is the content of my "Desktop" folder:

~/Desktop$ ls -al

The system is nearly 3 years old (Intel Core2 Duo 2.4 Ghz CPU, 2 Gb RAM, Nvidia 7600GS) , but works fine for required applications (after the login is completed).

Thanks.

The above commit should fix this problem, but if you still see it in KDE 4.4 beta 2, please reopen this bug report.

Thanks.

Hi, 
I've installed KDE 4.4 beta 2, and the "Folder View Widget" works very fast with the "Desktop" location.

Thank you very much.
