Kolab and Kontact on Mandrake 10

[Fausto Zorzi - NetiX s.r.l.]

Hi, I'm trying to configure Kolab server and Kontact as its client on a 
Mandrake 10, purchased as a PowerPack+ package.
The Kolab server installed with no problems, since everything needed was 
  already there, it starts and stops well.
The problems arose when I tried to configure Kontact to use it as a 
client. First I tried to configure that following the little 
documentation that comes with the package, than the Mandrake support 
told me to refer to an on line document:
http://www.klaralvdalens-datakonsult.se/?page=projects&sub=groupware
I followed the Advanced Server Setup wizard as indicated, but when I 
reach the section in which I have to select the folder in which to store 
the groupware subfolders and press "Next", the program crashes; when I 
try to get the backtrace for the crash, I got the following message: 
"This backtrace appears to be useless.
This is probably because your packages are built in a way which prevents 
creating of proper backtraces, or the stack frame was seriously 
corrupted in the crash."
I also tried to follow the manual configuration, first starting KMail 
without groupware functionality, then going in Settings->KMail 
Configuration, but the "Groupware" folder at the bottom of the dialog 
mentioned by the document is not there.
Can someone please help me?
Thank you in advance.
