I don't know what caused this but it seems an update broke my libmagick somehow.
I have a couple of programs that used to run without troubles (using Imagemagick of course, Magick++ precisely).
But now they fail to load or save images.
terminate called after throwing an instance of 'Magick::ErrorMissingDelegate'
what(): tsp-test: no encode delegate for this image format `render.png' @ error/constitute.c/WriteImage/1153
I'm confident it's not related to my programs since 'convert' also fails:
convert: no decode delegate for this image format `28675.jpg' @ error/constitute.c/ReadImage/533.
convert: missing an image filename `28675.png' @ error/convert.c/ConvertImageCommand/2940.
I tried googling this to no avail, I could use some pointers.
