소프트웨어 센터가 실행되지 않습니다

우분투 그놈 13.04 설치한 후 PPA 추가해서 그놈 3.8로 업데이트 했습니다. 그런데 소프트웨어 센터를 실행하면 바로 창이 닫겨버리네요. 터미널을 통한 프로그램 설치는 정상적으로 가능합니다. 아래는 터미널에서 소프트웨어 센터 실행 시 나오는 메세지입니다. 도와주세요.

(software-center:3048): Gdk-ERROR **: The program ‘software-center’ received an X Window System error.
This probably reflects a bug in the program.
The error was ‘BadDrawable (invalid Pixmap or Window parameter)’.
(Details: serial 2017 error_code 9 request_code 62 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
