I have just noticed that my submission was reshaped as a Phonon bug. So is this a known problem? Should I add details of my Phonon configuration? Regards, A.M.
Yes, please. Also, you need to install the debugging symbols for phonon and the phonon-backend-vlc, else your backtrace is not really helpful. Please see also https://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports
Uhm, as yet I did not understand from which repository I should download the debugging symbols for the two required packages, could You please be more specific? Meanwhile please find below the output of "sudo zypper se -is phonon": S | Name | Type | Version | Arch | Repository --+--------------------------+-----------+-------------+--------+------------------------- i | libphonon4 | package | 4.8.1-2.4.1 | x86_64 | openSUSE-13.2 Update-Oss i | libphonon4qt5 | package | 4.8.3-2.8.9 | x86_64 | openSUSE-13.2 Update-Oss i | phonon-backend-gstreamer | package | 4.8.0-2.4.2 | x86_64 | openSUSE-13.2 Update-Oss i | phonon-backend-vlc | package | 0.8.0-2.4.1 | x86_64 | openSUSE-13.2 Update-Oss i | phonon4qt5-backend-vlc | package | 0.8.2-2.8.1 | x86_64 | openSUSE-13.2 Update-Oss i | python-kde4-phonon | package | 4.14.3-8.2 | x86_64 | openSUSE-13.2 Update-Oss
(In reply to Andrea Malfagia from comment #3) > Uhm, as yet I did not understand from which repository I should download the > debugging symbols for the two required packages, could You please be more > specific? those should be in the regular repositories where the other packages are, did you check the link I gave you? It has a link to your distribution details about debugging symbols :)
Well, actually, when the guide you linked comes to referencing the KDE repositories, it points to an obsolete page. By googling I arrived here: https ://en.opensuse.org/SDB:KDE_repositories which looks like a rather messy page. Anyway there I found a link to what is called sort of "KDE Extras for openSUSE 13.2": http://download.opensuse.org/repositories/KDE:/Extra/openSUSE_13.2/ However, in the packages listed here I see nothing like "phonon-debuginfo" or "phonon-backend-vlc-debuginfo" :-/

That can all be found from the second link in our techbase article. If the openSUSE pages are incomplete, please report this to the distribution, that is out of my reach.
Eventually I got the debug packages following your latest link, thank you! But now things are getting weird: while comparing the debug packages with the versions of the installed ones, at a certain stage I somehow had to uninstall phonon-backend-vlc, and as a consequence digikam started to work! I mean that, once crashing, once locking up, it eventually went on to apparently full functionality, were it not for crashing upon exit, which I suppose is now an entirely different problem o.O
Thank you for the fast feedback. Closing as invalid, as the bug report is of no more use. Please report the crash on exit with a backtrace, I guess it is probably digikam related, not to the phonon backend, then.
Sorry for replying late, but unfortunately I cannot provide a significant backtrace, at least at present: when the problem occurs, the reporting windows shows the messages "Application: digiKam (digikam), signal: Aborted" and after further inspection it adds that there is no useful information available (I don't remember the exact phrasing). I will try to be more precise after further investigation.
Not reproducible since digiKam use QtAv framework + ffmpeg to handle video files.
