dconf-editor dropdown menu items are too wide

[PJSingh5000]

The drop-down menu items in dconf editor are too wide. In most cases, when clicked, they extend from the left edge for the screen all the way to the right, even when the content is only a few characters wide.

Here are two examples (schema and key)...

com.canonical.Unity.Launcher launcher-position
The options in the menu drop down are "Left" and "Bottom".

org.gnome.gedit.preferences.editor background-pattern
The options in the menu drop down are "none" and "grid".
A screen-shots is attached.
