cannot import pfam format files with tab separators

I picked an arbitrary page from PANDIT to try and load an alignment from:
http://www.ebi.ac.uk/goldman-srv/pandit/pandit.cgi?action=browse&fam=PF00903&field=nam-dsq

Copying and pasting the alignment data directly into Jalview or importing via a text file lead to an 'unsupported format' message, however checking with the Identify.main routine and stepping through with a debugger the PFAM parser extracts valid sequence data.

It looks like the 'hasValidSequence()' method is too strict to allow the data from this page to be imported.

-- Correction

After trying a simple test datafile - it seems all PFAM files imported get rejected by the hasValidSequence() test
