opening certain emails cause crash and core dump (no crash report). SOLVED Caused by HarfBuzz OpenType text shaping engine
when opening some (not all) emails, Thunderbird just dies (Arch Linux) with the following console dump:
thunderbird: hb-machinery-private.hh:642: void hb_lazy_loader_t<WheresFace, Subclass, Returned, Stored>::set_stored(Stored*) [with unsigned int WheresFace = 1; Subclass = hb_table_lazy_loader_t<1, OT::GDEF>; Returned = OT::GDEF; Stored = hb_blob_t]: Assertion `instance == nullptr' failed. Aborted (core dumped)
I have no idea what is different about the problem emails, but they make it crash every time they are opened.

I have rectified this, my system had genuine windows fonts that were killing harfbuzz. Have reported upstream: https://github.com/harfbuzz/harfbuzz/issues/1133
