Public bug reported:

When making a preview, and I've made an error, the preview fails to
render, as it should.

But sometimes there are some changes (e.g. when including lilypond files
or code, using lyluatex) that require the file to be compiled before a
new preview can be shown. When forgetting this and live preview is
enabled, the changes I've made don't show up when I save the file.

But since I upgraded to ubuntustudio 19.04 when I forget about it, and I
compile the file after an attempt to make a preview is made, kile tends
to throw the message '[ViewPDF] Please disable the live preview before
launching this tool' when I click on ViewPDF, while live preview is
actually disabled.

When checking the preview again it shows the pages to the last changes,
but after that blank pages. My guess is, that the process to build the
preview is not stopped when I disable 'live preview'.

But exiting Kile is not enough, when relaunching kile the message
persists and the preview is stuck as what I described above, the message
remains the same when I click on ViewPDF.

When looking at the processes on my PC, it shows that Kile is still
running, while I have closed it. Killing the process does not work. It
doesn't actually kill it, the process still exists, just doesn't use cpu
nor memory. A new instance of Kile can run though. But to get rid of the
zombified process, I have to reboot.
