Thanks for the bug report.  I'll make sure it gets fixed for the next 
ASE release.  For now, I think you can work around it by giving a 
filename like "abc.xyz", "abc.traj" or some other name with an extension 
that ASE knows about.  See table on this page:

     https://wiki.fysik.dtu.dk/ase/ase/io/io.html

Does that work?
