SUMMARY

Whenever I open dolphin with previews enabled, kdeinit5 crash. Stupidly enough, if I click to report the error I get a message that I can not, as there is not bug reporting address, so the error can never be known or fixed! WTF?

STEPS TO REPRODUCE
1. Open Dolphin with previews enabled
2. crash happens, everytime
3. 

We are sorry, kdeinit5 closed unexpectedly.
You cannot report this error, because kdeinit5 does not provide a bug reporting address.

OBSERVED RESULT
Executable: kdeinit5 PID: 10908 Signal: Segmentation fault (11) Time: 2019-02-28 10:56:29

EXPECTED RESULT

No crash of kdeinit5


SOFTWARE/OS VERSIONS
Fedora Linux 28, up to date
KDE Frameworks 5.54.0
Qt 5.11.3 (built against 5.11.3)
The xcb windowing system
dolphin 18.08.3

ADDITIONAL INFORMATION
This has been like this now for a long time, even after multiple updates.
Comment 1 Christoph Feck 2019-02-28 10:28:04 UTC
This might be fixed with 18.12.3 (released next week).

If you find the video file which causes the crash, I suggest to provide a link to it so that a developer can verify.

Comment 4 Christoph Feck 2019-03-12 18:05:50 UTC
Could you please test again with ffmpegthumbs from KDE Applications 18.12.3?
Comment 5 andreas.davour 2019-03-14 08:32:42 UTC
It looks like nobody have built any newer packages for my distribution yet, and it even looks like Fedora 29 is not yet provided with 18.12.3 so I would love to test, but will have to wait for those new packages.
Comment 6 Rex Dieter 2019-03-14 14:51:13 UTC
Feel free to grab newer package from
http://koji.rpmfusion.org/koji/buildinfo?buildID=10645
to test.

(though it should be showing up in updates-testing soon)
Comment 7 andreas.davour 2019-03-14 18:12:14 UTC
That version looks fine! Now it behaves just like expected.

Many thanks Christoph for the fix, and Rex for the package rebuild. Much appreciated.
