Opening a file from a windows network share

Hi to all,

I can confirm that problem:

Quanta is NOT able to open a file on an cifs (smbfs) share for READING!
However, it is possible to create a file and SAVE it in an cifs (smbfs)
share.

All other applications (kate, kwrite, qt-creator, ...) work as expected.

Here is my environment:

Kernel:  Linux 2.6.34.4-0.1-default i686
Distribution:  openSUSE 11.3 (i586)
KDE:  4.4.4 (KDE 4.4.4) "release 2"
Quanta: 3.5.10 (KDE 3.5.10 "release 41" openSUSE)

fstab entry:
//10.110.13.172/intranet$       /mnt/idefix/intranet    cifs
credentials=/etc/samba/.credentials_for_idefix_intranet,rw,uid=gerhard,gid=users,dir_mode=0755,file_mode=0664 0 0  

As Quanta is currently a KDE 3.5 application and Ruben and I are running
it under KDE 4.4, I suppose some KDE3 part/library is missing.

Does any one know what part this could be?
