Comment 1 Albert Astals Cid 2013-09-21 15:23:52 UTC 
I understand you say it crashed while refreshing the file, not that it crashes every time you open that file, right?
Comment 2 Thomas Dreibholz 2013-09-26 09:13:04 UTC 
Yes, Okular crashed when updating the PDF file.
Comment 3 Albert Astals Cid 2013-09-26 18:21:13 UTC 
Going back to unconfirmed (it's one of those one off hard to repro crashes that needs lots of deep investigation and some luck to fix)

okular (0.17.2) on KDE Platform 4.11.2 using Qt 4.8.5

- What I was doing when the application crashed:

Okular was searching for a word, when I recompiled the tex document that corresponds to the PDF file. Okular continued to search, even though the document was not visible. After the compilation finished, it crashed with the attached backtrace.

okular (0.17.2) on KDE Platform 4.11.2 using Qt 4.8.4

- What I was doing when the application crashed:

Okular was sitting on my other monitor, but I guess that the PDF got reloaded (due to auto-build feature) as I was working on its sources.

Comment 6 Maarten Bezemer 2013-10-18 14:45:42 UTC 
Sometimes the document gets reloaded, but all pages are black. Which is solved after a second (automatic) reload.

It is possible that Okular is reloading the document too early, before the PDF writer is finished outputting it? Resulting in crashes (due to unexpected/missing content) or the black pages?
Comment 7 Albert Astals Cid 2013-10-18 14:52:28 UTC 
There's no way to know if the pdf writing has really finished, so we try to reload the file if it has not changed in the last X seconds.

okular (0.17.2) on KDE Platform 4.11.2 using Qt 4.8.4

- What I was doing when the application crashed:

Editing a document with LaTeX. The PDF I was viewing in Okular was recreated by pdflatex. Okular crashed upon refreshing the PDF.

Comment 16 Albert Astals Cid 2014-05-08 11:01:15 UTC 
Can any of you guys that could reproduce this bug please try with Okular >= 0.19.0 ( KDE >= 4.13.0 ). I know i fixed some bugs regarding refreshing of files and i think this one is one of them.

Thanks for caring about Okular :)
Comment 17 Albert Astals Cid 2015-07-09 20:34:48 UTC 
Since you didn't come back to us we hope it was fixed meanwhile :)
