--- Comment #8 from Henrik Fehlauer <rkflx at lab12.net> ---
Doesn't look like it's related to bug 340619 (which is about calligra, but we
crash in synctex).

Possible duplicate: bug 383980 (although there it crashes in
_synctex_free_leaf(), while we crash in _synctex_free_input())

I can reproduce the bug with empty.synctex.gz and an ancient Okular 0.21.1 on
KDE 4.14.4, too. Maybe there's something in luatex / TeXLive which changed
recently (no reports since several years, now two within days)? 

Unfortunately this is not solved by D7495 (which is about trying to reload
again when the previous reload is not finished yet), as the first crash (close
Okular without pressing F5) segfaults in synctex without entering
slotDoFileDirty().

Flupp: I don't think we need another backtrace, but if you are interested
anyway, have a look at [1]. Seems like on Arch you'd need to recompile for
yourself.
