Gnome 3 Freeze. Believe Extension related [Solved]

[nobicycle]

Hi,
On a Weekly repo updated Sabayon, Gnome 3 freezes 2 to 3 times per day. When I switch to the console I observe with htop, gnome-shell at 100% CPU and one (of 2) CPU at 100%. Kill, Ctrl-ALT-F7, forced logout, and I can login again.

I have a few (8) Gnome-shell extensions enabled and believe one of these is the cause, probably the Media Player extension.
Obviously I've tried disabling all extensions, and that works. But finding out which of the 8 extensions or combinations thereof is the cause is difficult.
How can I debug this situation better and find out what triggers gnome-shell to go to 100%?

Thanks for replies.

In fact, GNOME3 have near one year and remains unstable and not practical...
GNOME-Shell is higly sensitive to video board, ant to minimal modifications, and freezes out frequentely.
Today works, tomorrow, not...
these issues are the main reason for that i dislake GNOME-Shell.
if you install another graphical env., as XFCE (GNOME Shell compatible) you may choose in the login, begin new sessions and try to solve the problems carried out by GNOME3.

Thank you Alberto.
It must have been one of the extensions. I reduced them to a minimum and the poroblem went away.
Agreed about the Gnome "less is more" fiasco.
