Solved, and thanks for the references.

Mystery solved?
X11 preferences >> pasteboard >> Enable Synching [+]

When enabled only raster is clipped to be pasted anywhere in the OSX environment.
When disabled, objects' attributes are copied.

Is this an issue to tackle with X11? Whom with?

What am I using:

Macbook pro
OS 10.9.4
XQuartz 2.7.7 (xorg-server 1.15.2)
inkScape 0.48

Hello.

When I copy a vector object (a path, text, shape, etc) and paste it into a new inkscape window, all editable attributes are lost.
What is actually pasted is a raster image.

Any ideas?
