Version: 2.2.0 (using KDE 4.3.2) OS: Linux Installed from: Ubuntu Packages when i do a librivox search for a book, there are no search results displayed, however wireshark shows me amarok is constantly querying the librivox server (and is getting a correct answer, too). furthermore, running amarok with the debug option set produces an output that is repeating the insertItem thing over and over again as soon as i try to expand the search node, amarok crashes
Created attachment 38878 [details] Output of amarok -debug
Created attachment 38879 [details] screenshot of the search
Could you please upgrade to Amarok 2.2.1, available in the kubuntu backports PPA and see if this changes the behavior?
hello myriam, i upgraded to 2.2.1 and still no search results... it keeps crashing on expanding the query node as well, however it doesn't usually do so on the first click (on the little +). it takes a "random" number of clicks to crash, but it crashes eventually
Thank you for the feedback.

Hm, seems I forgot to ask you for a backtrace.
