When selecting "Find File..." in kpackage, a window is popped up allowing you to specify a file name. When you specify a file name and click on the Find button, the following error messages are always generated by kpackage: Kprocess error: Cann't start dpkg followed by: Kprocess error: Cann't start kiss Note that the mis-spelling of can't is also a part of the actual displayed message (an uncorrected typo?). The RPM I used to install kpackage is: kpackage-1.3.8-5. Note that this package is not in the list of packages defined in BUGZILLA (another problem).
Fixed in 1.3.10-3.
