Hi all,

I am using amarok 2.0.1.1 on a ubuntu 8.10 machine, installed from Ubuntu ppa's repository. Yesterday, all KDE related libraries were updated for my distro and after that I am not able to start Amarok again. I get the following output:

$ amarok

Probably, it is a phonon issue, but how to find out? Sound works perfectly on any other application I use (but these other apps are gnome applications, I have to say). How could I check what is the issue here?

Without a crash backtrace, we can hardly tell you anything useful, sorry. Also, you may start Amarok with "amarok --debug" from the shell, to gather more information.


Please see here:

Having the same issue after upgrading from Intrepid to Jaunty Alpha 5. Amarok worked fine the first time it ran, but after a right-click -> quit and trying to start it again, the same crash happens for me.

I installed:

Code: Select all

sudo apt-get install amarok-dbg libc-dbg phonon-dbg kdelibs5-dbg pulseaudio-dbg

And got the following backtrace:

Code: Select all

Application: Amarok (amarok), signal SIGSEGV

Should we report this as a bug?

For me, this was solved by installing phonon-backend-xine

motin,

Thanks for the suggestion. I ran into exactly the same problem with an identical call stack.

Installing phonon-backend-xine resolved the problem.
