Sen2cor: KeyError: 'gfs'

Optical Toolbox sen2cor

Working on scene: S2A_OPER_PRD_MSIL1C_PDMC_20160721T120203_R060_V20160721T021833_20160721T021833.SAFE

It appears the error is being thrown because the .gfs file type is not listed as a file type in this line of code taken from L2A_Manifest.py:

def getMimeType(self, href):
    """
    Returns mime type function of file extension
    """
    dicoMimeType = { 'xml': "text/xml",
                    'gml': "application/xml",
                    'html': "octet",
                    'xsl': "octet",
                    'jp2': "application/octet-stream" }
    return dicoMimeType[href.split(".")[-1]]

This file throws the error for me:
GRANULE/S2A_USER_MSI_L2A_TL_SGS__20160721T090523_A005634_T50JLL_N02.04/QI_DATA/S2A_OPER_MSK_TECQUA_SGS__20160721T090523_A005634_T50JLL_B01_MSIL1C.gfs
