Gthumb don't run after update

[Balgkarbr]

Hi, my name is Leon, i am using Xubuntu 12.10 on my desk and 13.04 on my laptop, both 64bit- both with XFCE devel 4.12 ppa.
An everything is fine when i make a update after install this ppa "ppa:webupd8team/gthumb " and then Gthumb stops work, but in the real problem is that all ppas from webupd8team in past week cause the same problem, gthumb don't work.
The, i remove the PPA "ppa:webupd8team/gthumb " update de system again and install gthumb without that ppa and gthumb back to work.
And this is happen to me with my note and desk, in my desk i use intel and nvidia and in the lap im using amd and ati.
On desk is the kernel 3.7.5 and in the lap is the 3.8.05
I hope this could help.
