I'm starting libreoffice with an docx document and it immediately crashes outputting the following text on console. The file opens fine on a different computer with an older libreoffice version.

This as been fixed upstream at https://bugs.documentfoundation.org/show_bug.cgi?id=118373 and reported also by other users at https://forum.ubuntuusers.de/topic/upgrade-von-16-04-nach-18-04-libreoffice-oeffn/

Workaround: disable OpenCL software emulation and Java Runtime in Options.

[Olivier Tilloy (osomon)]

That error message and the crash are most likely unrelated (according to the upstream bug report, the error message is harmless). But I see that your architecture is i386, and you mention that disabling java in the options fixes the problem, so the issue is most likely bug #1699772.
OpenJDK 11 is being backported to Ubuntu 18.04 (see bug #1814133), and this crash has been confirmed to be fixed with it, so if everything goes well you should soon be getting an update that will fix the crash.
