Hello,
take any jpeg image with exif profile and no other profiles, and run this:
convert -set Jpeg:colorspace "" -set Jpeg:sampling-factor "" image.jpg image.png
Then, "identify -verbose image.png" will fail the assertion when
calling GetValueFromSplayTree() in property.c, line 1416. The
intention is, obviously, to test whether the property already exists,
but for the first property image->properties will be NULL. The fix is
below.
Index: property.c
