[Tikzdevice-bugs] Question about warnings

[Charlie Sharpsteen]

HI Lorenzo,

I just installed tikzDevice 0.5.2 and ran it using the versions of R and TeX
Live provided by the Ubuntu repositories.  I was able to run through all of
the plots in our test suite without observing the behavior you are seeing.
 I also don't have any good ideas as to where to look for a change that may
have caused this message.  The cumulative diff between versions 0.5.1 and
0.5.2 shows that we did not make any changes that directly affect the way
metrics are calculated:

If you have a sample of code that reproduces the behavior, I would love to
check it out and see if I can figure out what is happening.  Otherwise, I'm
pretty stumped as to what is causing your warning message.
