Banshee 2.6.2 stop working in Fedora 21/22 x86_64 gnome desktop 3

[kauyumari]

This is really weird, I have been using banshee for several years, and yesterday it stops working.
I mean, I let it opened and this mourning I click the play button and it began sounding but the the banshee window stopped responding. I can select the window but not scrolling, not stop. No button woks.

I reboot my system and at launching banshee, the same freezing after clicking play, I erase the banshee-1 trees in .cache and .config subdirs and nothing.
I updated the fedora 21 reboot, and  I got the same freezing.
I really love this media player (I like good sound and the equalizer). I decide to upgrade to fedora 22, but I am still getting the same freezing after clicking play. I mean, it begins playing music but becomes inoperative.
if I try to down the volume with the keyboard keys, it stops sounding.
If I go to the top bar and try to quit I got the message:
"some song is not responding" wait or force quit.

If I wait and run top I notice that banshee is taking three of my cores (363%, also noticed by the sound of the fan)

If I start it at terminal as

%banshee -d
I get at launching a lot of:

(Banshee:10590): GLib-CRITICAL **: Source ID 986 was not found when attempting to remove it

but the banshee window is still working.

And after clicking play I get:

Note: Applications can use GLib.ExceptionManager.UnhandledException to handle the exception.
