Ok, I wasn't precise here. You're running LibreOffice with the kde4 backend:

LibreOffice has an internal list of priorities for the VCL backends, based on
the detected desktop. You can tell it your preference via SAL_USE_VCLPLUGIN,
but if that isn't available or fails to load, it will be ignored and the
fallback list tested, so LO can start at all. You can only be sure what you're
running LO with, if you check the VCL value in "About LibreOffice".

Ok - but still it's kde4: the linked crash lists the libQtCore.so.4.8.7 in the
backtrace. And the backtrace is totally different.

But all this proves my suspicion that maybe LO is using some Qt5 or KF5
function, which isn't actually available in your old libraries. LibreOffice
tries to load the plugin library (libvclplug*.so) but that fails.

I don't know how that could help.
BTW: for 6.2 the fallback list is: kde5, gtk3_kde5, kde4, gtk3, gtk, gen.
