Hello,
I have an issue using the Magick::Image class.
Sometimes, when I try to retrieve a GIF image using an url the constructor fails, an exception is thrown and the following output occurs on stdout:
Magick: no decode delegate for this image format `//www.nn4d.com/images/ms/free_symbol_ids/ ... 4_1028.gif' @ error/constitute.c/ReadImage/532
The image url I'm giving to the constructor is http://www.nn4d.com/images/ms/free_symb ... 4_1028.gif
When I download manually the image and I give the path to the constructor of the class I have no error and the image is successfully loaded.
I thought that GIF decoding was built-in in Magick. What can I do to solve this issue?
Here is the convert -list configure result:

Notes:
--> I have already experienced this issue. The only way I had to solve it was to rebuild and install the library.
--> I did a make check and all tests passed successfully
Thank you for your help!!
