Two things more:
1. My comment above is obsolete anyway, as the new LO does not use sensible-lomua any more. It talks directly to the ExternalMailer.
2. It still does NOT work here (Ubuntu 14.04, LO 4.2.4). Thunderbird is opened after "Send email as ODT", name is filled in, but there is no attachment added.
I can NOT confirm that this bug is fixed.
