Amarok causes gnome-shell to crash

[monochromec]

The subject says it all: when quitting Amarok, the surrounding gnome-shell is restarted.

Apparently, something sends a SIGABRT to the shell:

Amarok seems to end normally as --debug tells me but invoking it from the command line produces the same effect as from within the shell: it restarts.

More than happy to send more info as required.

The gnome shell seems to be the only environment affected by this issue - I tried Plasma, Cinnamon, XFCE and Mate. None of them crash when Amarok exits.

Apparently this is caused by a rogue Gnome Shell extension. Running gnome-shell inside a gdb session reveals the following BT after the crash:

Please close this one as I filed a new, more fitting bug report: https://bugs.launchpad.net/ubuntu/+source/gjs/+bug/1718993.
