I haven't seen those warnings  so soon in a script. Can you tell me if 
the 'sniff' utility works?

The above line doesn't look right at all. Can you paste the output of 
the 'locale' command? I'm guessing your locale is breaking dogtail's 
automatic runtime translation.

The above traceback is due to the fact that the runtime translation 
isn't working properly.

The above warning messages are pretty benign, considering the script has 
already run to completion. If you ever see them in the middle of a 
script, I'd be worried.

The messages appear on all architectures, just not all the time.

It looks like the difference here is probably your locale. On ppc64 you 
were using some form of en_US or en_GB, correct?

I've seen those messages before (but never where you saw them) and 
they're generally not a good sign. The first step is telling me what 
locale you were using, so I can try to reproduce.

Hopefully we can get these problems solved, so you can get some good 
testing done :)
