[Comment from a bug triager] The crash looks related to the Now Playing widget, if you can repeat the crash at will, install the "kdeplasma-addons-dbg" package and try to generate a new backtrace. Thanks (In reply to comment #1) > [Comment from a bug triager] > The crash looks related to the Now Playing widget, if you can repeat the crash > at will, install the "kdeplasma-addons-dbg" package and try to generate a new > backtrace. > Thanks You're right, Plasma crashes each time i quit Amarok. I have two instances of Now Playing widget, on desktop and taskbar. I installed the debug package, however crash dialog doesn't appear anymore. Would you like me to create the backtrace with gdb? yes, please do. something you can try that might make it easier is to run: plasmoidviewer nowplaying ... that should run it in a small window. then try to trigger the crash with amarok. (In reply to comment #3) > yes, please do. > > something you can try that might make it easier is to run: plasmoidviewer > nowplaying ... that should run it in a small window. then try to trigger the > crash with amarok. plasmoidviewer didn't crash.
