Sen2Three-1.1.0 Fatal error in import of band B02

I am getting a Fatal error when running the new version (1.1.0) of Sen2Three. This happens even when using the first three level 2a products suggested in Sen2three-1.1.0: release announcements post as inputs.

The report log suggests an error in band B02:

<inspection execution="2017-09-21 19:52:38,769" level="INFO" module="L3_Config" function="timestamp" line="1508"/>
<message contentType="Text">Procedure: L3_Tables: start import, elapsed time[s]: 1.448</message>

<message contentType="Text">Module L3_Synthesis deleted</message>
</check>

No other errors are reported in the log. I’m running with a fresh installation of anaconda & sen2three on Mac OS and have downgraded the libxml2 library as suggested in the installation posting. 2A Products are freshly downloaded and no other analyses have been carried out on them.

Any suggestions on how to resolve the problem would be very welcome.
