same problem here. installed fresh install of kubuntu 9.04. 
i cannot configure file sharing

1 - Logged in
2 - Started Dolphin
3 - Right clicked Pictures folder and selected Properties
4 - Selected Share Tab
5 - Selected "Configure File Sharing" button
6 - Request for password appeared - Entered password and requester disappeared with nothing else happening.


Then I started KPackageKit from the K Menu and installed kdenetwork-filesharing package.

1 - Right clicked Pictures folder in Dolphin and selected Properties
2 - Selected Share Tab
3 - Selected "Configure File Sharing" button.
No request for a password was made cause it had been typed in previously.

still nothing happens..


When I run "dpkg-query -l 'kde*' > packages.txt" nothing happens. When I run "dpkg-query -l 'kde*'" I'll get this:
james@linux1:~$ dpkg-query -l 'kde*' > packages.txt
james@linux1:~$ dpkg-query -l 'kde*'

james@linux1:~$

then as advised by "mugginz" I  execute the following command

kdesudo kcmshell4 fileshare

but same problem as above..i get this:

james@linux1:~$ kdesudo kcmshell4 fileshare
james@linux1:~$ 

what could be wrong? 

i have done a lot of googling and it appears that this has been a common problem for many people over a few distros.  my symtoms are exactly as  the op

i found this also http://kubuntuforums.net/forums/index.php?topic=3098941.msg159923#msg159923

i do not want to hand edit the smb.conf file to create the shares Iwant. :)

thanks in advance
