I suspect that what's happening is something like the gauge not being
100% ready to go when you're trying to fetch the value back out of it.
 When Hecl walks off the end of the main script, it goes into its
event loop, at which point the GUI has a chance to catch up.  IIRC, at
least, it's been a bit since I looked at that code:-)

If you were getting this result in a callback, I'd be a bit more
concerned about it.  I'll take a look later in any case to see what I
can see.
