> But okular regularly crashes, even if I don't do anything What does this mean?
It means that on an idle machine, okular crashes sometimes. I am sorry to have no more information, nor any way to reproduce this inconsistent behaviour.
that's really strange, do you have a backtrace for those "idle" crashes? About the one for reloading on pdflatex, can you reproduce it?
@Pierre : Could you share the related pdf file ( which you hit the bug ) with us (if it isnt something personal or private ) @Albert Astals Cid : I am just guessing that maybe just maybe ubuntu's systemd-oomd settings might causing this idle thing, something might cause huge memory allocation and oomd is killing okular to give system more resources [If i am not wrong ubuntu is only setting 1gb swap area and oomd's misconfigured for this settings which generally kills randomly applications]
