The interesting thing is that it opens the right libpython:

  
open("/gnu/store/7q9nn76r76hnxbfxyv6asishx58jc420-python-2.7.12/lib/libpython2.7.so.1.0",
 O_RDONLY|O_CLOEXEC) = 3

but then it does this:

… and from there, chaos ensues.

I’m not sure where those /usr/lib file names come from though.

Note that Scribus hard-codes a whole bunch of program file names (not
that of ‘python’, though), which may lead to problems down the path, at
least on GuixSD:

./scribus/ui/prefs_paths.cpp:   profileDirLineEdit->setToolTip( "<qt>" + tr( 
"Default ICC profiles directory. This cannot be changed with a document open. 
By default, Scribus will look in the System Directories under Mac OSX and 
Windows. On Linux and Unix, Scribus will search $home/.color/icc, 
$home/.local/share/color/icc, /usr/share/color/icc and 
/usr/local/share/color/icc" ) + "</qt>" );
