I get the same error when I try to start up ubuntu-tweak, but a slightly different backtrace:

Is this your first time to install Ubuntu Tweak?

If so, try to reboot your system and launch Ubuntu Tweak again.

Yes, it might have been. Or rather, I had an old version installed (ubuntu-tweak_0.4.4-1~intrepid1_all.deb), uninstalled it, and installed 0.5.4.1. I will try to remember to try again next time I reboot.

I got the same error log as Tyler Rick. But after a reboot, Ubuntu Tweak is running fine.
(I added the sources for Ubuntu Tweak stable, launched the update and got the crash when I launched Ubuntu Tweak again)
On Ubuntu 10.4

So I think reboot will fix most of the case, if anybody meet this problem, just try to reboot.

Running 0.5.4.1-1~lucid1 on Ubuntu Lucid and a reboot does not solve this problem for me. What information do you need?

@James Tait

Try to run this command in terminal:

sudo /usr/share/ubuntu-tweak/ubuntu-tweak-daemon

Then open Ubuntu Tweak in another terminal window, see the result, thanks!

@TualatriX

Thanks for the immediate response.

In my case as reported in the duplication bug (583598) the problem has been solved by editing the source list i added with gedit.
I have no idea why that solitary "n" character appeared in the source file, That could be another bug, but is not Ubuntu tweak related.

In case of UT it would have been great if it would have not crash because of a "bad" source list. My initial idea was to correct the source list with it, as it is extremely friendly at such tasks. But here i repeated myself.

Thanks for maintaining UT, one of the greatest tools i used.

Yes, I will soon fix this issue to make it won't crash because of bad sources.list.

And the same crash which reboot can fix it will be fixed too, :D
