EclipseIDE icon too big in Dash, not launching on being clicked

The icon for EclipseIDE in the Dash home is too big than what it is expected to be(See attachement). On providing a smaller icon image, it gets fixed. Seems like, 12.10 doesnt resize the icon images provided by users for custom items. This wasnt an issue with 12.04.

1) The release of Ubuntu I am using: 12.10
2) The version of the package I am using, via 'apt-cache policy pkgname':
xorg:
  Installed: 1:7.7+1ubuntu4
  Candidate: 1:7.7+1ubuntu4
  Version table:
 *** 1:7.7+1ubuntu4 0
        500 http://in.archive.ubuntu.com/ubuntu/ quantal/main i386 Packages
        100 /var/lib/dpkg/status

3) What I expected to happen: The Eclipse icon to be of normal size, and IDE to be launched on clicking.
