This must be a GCG format database, indexed in SRS ... you have gaps in 
the ".." format.

Ideally SRS would fix that ... but EMBOSS could cope with some small 
changes. Anyway, an SRS fix is non-trivial because it is reporting 
exactly the text that GCG stores.

Simplest in your case would be a script that changes ". ." to ".." 
before passing the data to EMBOSS.

Meanwhile, I will take a look at fixing this for a future release.
