error on nonframeshift deletion

[mpallocc]

Dear all,

we are experiencing this error on a non-frameshift deletion, ending with a stopgain (quite rare):

protein change: p.V340_*358del

varcode definition:

vv = Variant(contig=16, start=30128111, ref='CTGGGGTGGTAGAGACAGCAAGGCTCAGGCCTGGCATGGGGGATGCCTACGTGCCCCCCTGCTCCCCTGCCCCCAGCCCCACTGCTGCTGGGGACTGGCCCAC', alt='', ensembl='GRCh37')

vv.effects()

ValueError: If no amino acids added by StopLoss then it should be Silent

Seems to instantiate a StopLoss object and it raises error from there.
