Old kernel janitor in infinite loop

[Nick Payne]

Running 0.6.2-1 on 12.04 with all current updates. I also have the 3.4 rc3 and rc4 kernels installed from http://kernel.ubuntu.com/~kernel-ppa/mainline/ in addition to the 3.2.0-23 kernel. When I run Ubuntu Tweak, go to the Janitor tab, and click the checkbox next to "Old Kernel", the program never completes scanning for old kernels - the spinning hourglass just sits there until I close the program.

Hi, thanks for your report.

Could you run Ubuntu Tweak under terminal with debug mode, then do the old kernel scan operations, then give me the results?

Thank you.

Open your terminal, then run :

        ubuntu-tweak -d

Last part of the terminal output from running ubuntu-tweak -d
