Looking at this output, it seems Emacs is trying to dynamically link
librsvg.  Two issues spring to mind: First, this kind of linkage is not
that well supported by Guix, so we tend to substitute* the full path. 
Is this done for librsvg?  Second, there might be a (version) mismatch
between the librsvg Emacs expects and the one it gets.  Does
rsvg_handle_set_stylesheet actually exist as a symbol in your librsvg?

Cheers
