Just for confirmation that there are more than 10 people in Switzerland trying to install Kubuntu ;)
I experienced exactly the same "ubi-console-setup failed with exit code 141" with a Kubuntu 13.10 64bit ISO image, while trying to install it in a VirtualBox machine, on a Mac with OS X 10.8.5 as host and... a Swiss keyboard (DE_CH)!
The error appears when about to select the Time Zone during installation. "Retry" results (unsurprisingly) in the same error. After "Ignore" I reach the "Personal Info" screen (where I can enter my desired user name and such), the installer downloads some packages in the background and proceeds somewhat, until finally dying with an "Installation failed" message (about 25% of the progress bar or so have been reached).
Interestingly enough the system then goes on and boots into the KDE desktop - at this point I did not try to check what packages where missing (mostly because I was very annoyed by that black box which very frequently was rendered "behind" my mouse button, but that is probably more a Mac Hardware/Virtual Box thing - never mind).
