Short description of error
Normally when exporting an animation and then importing again it looks the same again, but when exporting using "Decomposed" Transform with "Use Blender Profile" the animation will look different when imported again.

Exact steps for others to reproduce the error

  1. Add an armature and parent the default cube with automatic weights
  2. animate the cube

  1. export to collada, select Anim > Transform = "Decomposed" and make sure Extra > "Use Blender Profile" is checked
  2. import that file again with default settings. (it's different)
  3. try again with "Use Blender Profile" unchecked (it works)
