Seems that it's crashing when handling "scrobbling" of audio files. It shouldn't try to scrobble anything if you don't have last.fm credentials entered though, which makes this one of those "shouldn't occur" bugs. You can see if you have last.fm credentials entered by going to "Settings -> Configure Scrobbling...". I don't have a last.fm account so if you *are* trying to use that feature I'll need to add the developer of that feature to this bug to troubleshoot. If you don't have last.fm credentials entered then let me know of that as well as I will have to try to debug further... Oops. You're right. I can remember it happens after I setup my Last.FM :( Martin, could you look into this crash bug relating to JuK's last.fm support? Please repost a backtrace with debug symbols. It is very hard to get debug symbols under Gentoo. I'll install another distro in the virtual machine next time. Okay, finally I got a backtrace with more details. Application: JuK (juk), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

/var/tmp/portage/kde-base/juk-4.11.0/work/juk-4.11.0/main.cpp:104 Is it enough? backtrace provided. Ah, it seems like this is because some of the optimizations done, the Scrobbler::m_networkAccessManager isn't initialized when post gets called. Should be fairly easy to fix. Git commit 1fc69df5578d2a34b36aff4ba43c4cfa30e829dc by Michael Pyne. Committed on 03/09/2013 at 01:14. Pushed by mpyne into branch 'KDE/4.11'. scrobbler: Change Scrobbler owner to be JuK, not PlayerManager. PlayerManager will always emit a track changed signal, which means the Scrobbler will always have to receive it even if we're not scrobbling (my last change to avoid making network requests when not using last.fm broke this, it seems). Instead move the Scrobbler into the base application class where we can track whether scrobbling is enabled or not, and Do the Right Thing. I don't have a last.fm account so although this should still work (I think), I can't verify. I have verified that we at least don't crash anymore. Martin, can you double-check when you get a chance?
