Warning while converting blender model with embeded DDS texture

Hi friends
I tried to pack my textures inside blender like this :

so that I have textures packed in my j3o file when converting.
It worked well for png , jpg .
for tga it worked but texture was looking dark on model .
but for dds textures i got this warning :

Apr 10, 2016 11:36:48 PM com.jme3.scene.plugins.blender.textures.ImageLoader loadImage
WARNING: Unable to load image using TGA loader!

I know I can convert dds to png then try to pack it. but it might be bothersome for models with much textures.(because there need to remap each in blender)
Everything works fine if i do not pack them .
It is not a must for me to pack my textures inside j3o but i just wanted to inform you about this issue.
