identify output containing lines with only whitespace leads to an exception in line 156 (today's master). The stdout from identify contains:
Profile-exif: 5153 bytes
Profile-xmp: 2895 bytes
I have removed some lines to shorten it, but this is only about the seemingly empty lines in the middle: they contain several tabs.
The failing image is one included by default with Windows7 (Koala.jpg). It is processed fine after the fix.
parseIdentify() skips empty lines and lines containing only whitespace.
