FWIW this will disappear from the next libreoffice coverity run because
I typically patch it with try {} catch (...) { std::terminate(); } to
ignore warnings from "externals", but on upgrade I temporarily lost
that. It will however still appear in mdds's own separate coverity
results, which I refreshed yesterday.
