KNIME crashses

newly installed KNIME crashes regularly, and without warning on a new i3 computer, newly installed Xubuntu Linux, without leaving a warning or a logfile. 

is there any way to remediate this? the strange thing is - under identical circumstances on ubuntu 10.10 this never happens.


Does it generate any error log files (hs_err<pid>.pid) in the working directory (could be your home folder or the folder from where you started KNIME)? Could this be related to some weird X mechanism (fancy 3D settings?)
