Hi Xavier,

we also stumbled over this error and resolved it in a similar fasion.
Also we have sent a bug report to debian:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=409188

The problem is that "$*" sends all command line arguments
as a single combined string to pymol's __init__.py.
The bug was "introduced" in the new debian package,
before there were no quotes.

Best.

Hi,
I am using the pymol package provided with Debian testing (0.98+0.99r).
When I am trying to run a script without the gui, i.e. pymol -c
foo.pml, I get the following error :

Traceback (most recent call last):
 File "/var/lib/python-support/python2.4/pymol//__init__.py", line 364, in ?
   invocation.parse_args(pymol_argv)
 File "/var/lib/python-support/python2.4/pymol/invocation.py", line
270, in parse_args
   options.deferred.append("_do_spawn %s"%av.pop())
IndexError: pop from empty list

I think I solved it by changing the last line of /usr/bin/pymol from
python2.4 ${PYMOL_PATH}/__init__.py "$*"
to
python2.4 ${PYMOL_PATH}/__init__.py "$@"

--X.
