I've reviewed / searched the posts in this forum and have found similar issues that indicate mixed libraries like glib and glibc, I don't believe that is the issue here. The reason being that I have compared the rpmpkg logs to a similar upgrade to F27 on a laptop where oo4.1.3 is running and opens with no problems and the Meld diff shows the same glib and glibc libraries and versions, also the same gtk libraries. Having reviewed the other posts I did a gdb backtrace on soffice.bin and that is attached for reference.
