Confirmed that it crashes in LibO 4.3.1 and master on Linux Mint. Doesnt crash in 4.2.5.

LibreOffice 184.108.40.206 rc - updating version
Major - crash
High - default is medium, bumped because of the regression
Unfortunately it's not bibisectable - not sure if it just doesn't affect the bibisect package (which would be strange) or if it was introduced after the last commit within bibisect.
The crash has been fixed somewhere between 4011b74eb7650a0eeb99d3acebb9ef60b0fcaab9..4aa9b041de3129f19b48e66d349f48657b73f33e on master, most probably 589ca2a5e88a976bb10e60fcb1e3e75f4aa2504e (fdo#79319: writerfilter: RTF import: support horizontal rule, 2014-07-17), which has been backported to 4-3 as well.
