Good work! Can you create a minimal example, providing nothing more than the code required to replicate this problem, then the two pp calls that generate the different outcomes? I'm not at home right now but will test this on multiple platforms using the same version of the modules in question. The last time I suggested someone use -x to solve this problem they were under the impression that this should be the default, or at least display a message at run time explaining things. I suggested that they raise this with the maintainers, but it doesn't look like this has happened. Perhaps we can address this concern.
