Comment 1 for bug 30754

Filelight is an extremely useful and cool tool, but it crashes every time on exit (breezy + updates, kubuntu-desktop, x86).

I believe that the package probably needs an update to fix this:

$ apt-show-versions -a filelight
filelight 0.99beta6-0ubuntu3 install ok installed
No unstable version
filelight 0.99beta6-0ubuntu3 unknown
filelight/unknown uptodate 0.99beta6-0ubuntu3

$ filelight --version
Qt: 3.3.4
KDE: 3.5.1
Filelight: 1.0-beta4

The latest (http://www.methylblue.com/filelight/#packages) is 1.0-beta6, and is supposed to fix many crashing bugs. This could be one of them.

Here's the crash info, though I don't think it'll be very helpful:
