I tried to report it using the bug tracker at http://www.mrmc-tool.org/trac/newticket but the system asks me to log in, and provides no means for registering as a new user. So, this is the bug (produced on a Debian Linux Squeeze running in a VirtualBox): launching the command mrmc dtmc x.tra x.lab produces the following error > ------------------------------------------------------------------- > | Markov Reward Model Checker | > | MRMC Version 1.5 | > | Copyright (C) RWTH Aachen, 2006-2011. | > | Copyright (C) The University of Twente, 2004-2008. | > | Authors: | > | Ivan S.
