I experienced a problem with GraphicsMagick when retrieving the image size with GraphicalFunctions::imageMagickIdentify().

The command executed by the system is:

'/usr/bin/gm' identify '/path/to/my/pdf/file.pdf'[0]

The result of the GraphicsMagick call is:

**** Warning: glyf overlaps cmap, truncating.
**** Warning: glyf overlaps cmap, truncating.
/path/to/my/pdf/file.pdf PDF 595x842+0+0 DirectClass 8-bit 1.4M 0.000u 0:01

My GraphicsMagick version is:

GraphicsMagick 1.3.16 2012-06-23 Q8 http://www.GraphicsMagick.org/

The problem is, that the first two lines are written to stdout, not stderr. This is obviously a GraphicsMagick issue but I'm wondering if we could implement a workaround by simply using the last line instead of the first line that is beeing returned?
