Fix a runtime issue on Blue Gene created by the new fconfig system
The new fconfig system is now preventing program execution on the Blue Gene/Q system. (Note: this is not @jadolfbr's fault. The problem couldn't reasonably have been anticipated before the changes went into operation.) It seems that some systems don't allow certain system calls, and this creates an unhandled exception when Rosetta starts asking for home directories and whatnot. Adding a try/catch block to handle this.
