Download tool partially hangs when space on harddisk runs out.

[houstonhilton74]

Binary package hint: firefox-3.0

 My harddisk was almost full and I downloaded a file that exceeded the capacity my harddisk could hold. When this happened, a dialogue came up telling me about critical lack of space. I deleted the partially downloaded file, and the download window's progress bars just hung even afterward. Yet I could download other files easily, but the progress bar was just frozen.
Specks:
Ubuntu Jaunty 9.04
3.0 Package
I expected the large download to cancel itself or let me cancel it, but it just hung.
