[QE-users] iotk cannot read Li PPs

Hi!
I'm relatively new to QE, but have been able to run small systems without
any problem so far. However, I'm having issues with all of the Lithium PPs
from the PS library. For some reason, the iotk routine is unable to
correctly read these PP, and always ends with the error message:

# ERROR IN: iotk_scan_begin (iotk_scan.f90:182)
# CVS Revision: 1.23
# FROM IOTK LIBRARY, VERSION 1.2.0
# CVS Revision: 1.23

# UNRECOVERABLE ERROR (ierr=-1)

namel=PP_GIPAW_CORE_ORBITALS

This is for a simple vc-relax calculation for Li2O. I see the Oxygen PP is
read correctly, but when the Li PP is going to be read (regardless of which
one I choose), this error comes up. Here's a sample input file:

&control
  calculation  = 'vc-relax'
  restart_mode = 'from_scratch'
  prefix       = 'Li2O'
  pseudo_dir   = '/home/espresso/pseudo'
  outdir       = '.'
  wf_collect   = .true.
  tprnfor      = .true.
  tstress      = .true.
