Using backwards search, the journal shows a complaint from KDirWatch on the
line immediately preceding the segfault.

--- Comment #3 from Flupp  ---
After some further investigations I suspect the problem is not related to
backward search at all.

If kile is passed a folder on the command line, then kile segfaults:

% /usr/bin/kile /home
zsh: segmentation fault (core dumped)  /usr/bin/kile /home
return value 139

For some reason okular occasionally tries to open a specific line in a folder
on backward search, but this is another issue.

Can you try to create a small test file that demonstrates the problem?
