Magick++: NoDecodeDelegateForThisImageFormat with ICO file

[bytep]

I'm using Magick++ as shared libraries (libMagick++.so.2, libMagickCore.so.2, libMagickWand.so.2) for our application which runs on Solaris 64-bit.

It works fine with JPEG, PNG and GIF images but when trying with ICO image, I got the above error.

Here is the piece of code that results in the error:

Blob blob(buf, image_size);
Image image(blob);

where the ICO image is read and stored in buf.

Here is my "identify -list configure" output:

Path: configure.xml

And "identity -list format" shows:
ICO* ICON rw+ Microsoft icon
ICON* ICON rw- Microsoft icon
PICON* XPM rw- Personal Icon


In short the binaries works. I can use "convert" to convert ICO to JPEG.

So does Magick++ does not support ICO ? Or am I missing something that causes ICO handling to fail?

Any help is highly appreciated.

Problem goes away if calling magick() b4 calling read(blob)
