Care to provide full backtrace or maybe even full log? :) These function do that they should - fails because of incorrect parameters - pDescr=(nil). The question is where this NULL come from.
It's got a download available, if you'd like to try it yourself. I won't be at a linux box until tomorrow or so, so I can't get the log ATM.
