Scrolling switches tabs but doesn't refresh their contents

Version: 2.0.0-1ubuntu2 (using KDE 4.3.2)
Compiler: gcc/g++ 4.4.1-1ubuntu2
OS: Linux
Installed from: Ubuntu Packages

Steps to reproduce:
1) open at least 2 tabs in left or right panel
2) move a mouse pointer over one of tabs and scroll

What happens:
Tabs seems to be switching (the active one is changing when scrolling) but their contents doesn't refresh (they still display the previous tab files and directories).

What should happen:
Tab contents should adjust to tabs one switches to by scrolling.

Krusader 2.0.0 under KDE 4.3.2 (from kubuntu 9.10 repos)

Switching the tabs by turning the mouse wheel correctly changes the highlighted tab but doesn't change the content of the open tab. Furthermore if I then navigate within the tab to a different directory the background tab tag changes.

Everywhere else in KDE switching tabs with mouse wheel works as expected.

Maybe there is a missing reaction to some tab change signal.

Seems to be fixed in 2.4.0-beta1 "Migration", can't reproduce.
