Comment 3 for bug 1447131

the crash appears to be related to the resolution information embedded in the file.

for the file lighthouse.tif, the resolution is reported as 72dpi in Windows Explorer, and the file image-resolution.cpp in the routine readmagick() reports image.xResolution() = 72 as expected.

for the file choppoint_logo.tif, the resolution is reported as 300dpi in Windows Explorer, and the crash occurs somewhere in the routine ImageResolution::readmagick(char const *fn).
