Summary: pix_buffer open crashes with wrong extention
Initial Comment:
PD crashes if I forget to change the extention of a file in the "open" message to pix_buffer.
If the file is a test.jpg, but I try and open test.tif pix_buffer (imagemagick) crashes PD. It would be better if we got an error message about the file not existing.
Here is the bt:
pd: magick/exception.c:932: ThrowMagickExceptionList: Assertion `exception->signature == 0xabacadabUL' failed.
Program received signal SIGABRT, Aborted.
