I just did a fresh install, ran the update and installed gparted.
Gparted shows in my XFCE menu and it seems to crash start 
Anyone an idea what that could be?
UPDATE: I uninstalled and re-installed gparted and now it shows up.
Will do the same with clementine.
UPDATE: clementine is a no show, after uninstall and re-install
Hi Dirk,
GParted or Clementine? GParted requires the root user password.
Bill
in the update I wrote that after uninstall and reinstall gparted works noe and it always asked for the root password.
However, clementine is a no show
Have you tried to add it to the menu manually? Start with
whereis clementine
Bill
Hi,
If you start clementine in console what is the error message ?
clementine: symbol lookup error: clementine: undefined symbol: _ZN6google8protobuf8internal13empty_string_B5cxx11E
Thanks for helping 
OK Cool, I have the solution !
It’s a problem with the recent upgrade of GCC.
Rebuild all deps compiled with GCC5. before run an eix-sync.
All in root :
eix-sync
revdep-rebuild --library 'libstdc++.so.6' -- --exclude gcc
There are 270 packages for me.
After it completed, run clementine : done !
(The problem concern others apps)
Hello again, and thank you so much, did:
eix-sync
revdep-rebuild --library 'libstdc++.so.6' -- --exclude gcc
and then I ran emerge clementine and it is now up and running 
Thank you so much
Dirk
cool
