"top" core-dumps when console window is shrunk

[monstermunch]

Hi,

Sorry, I'm not sure what package to report this to. In Kubuntu Gutsy, do the following:

* Run konsole or xterm with a regular sized window.
* Run "top".
* Shrink the window as small as it will go (it will work if you just make it short sometimes too).
* "top" will now report that it has core-dumped.

This is the output I get after doing this:
