I commited today two fixes to the KDE SVN to make KDBus usable again on DBus method calls:
- fixed show the input widgets for input/output method parameters, show in the 'Output:' section only the output and not again also the input parameter widgets [1]
- fixed handling of boolean method parameters, now you should be able to call e.g. SetPowerSave(bool) on the org.freedesktop.Hal.Device.SystemPowerManagement interface again without errors [2]
Updated RPM packages are already available for openSUSE 10.2 - openSUSE Factory and SUSE Linux Enterprise (Desktop) 10 as always in my openSUSE Build Service project.
