[Bug 31200] [Dapper] Notification bubble cuts the icon

[Trouilliez vincent]

Public bug reported:

Affects: rhythmbox (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
Pic attached.

Most of the time, there is only one line of text in the bubble, and this
is not enough to see the entirety of the icon: the bottom of it is
clipped.

If the song name and/or artist name is very long, and occupy 3 lines of
text, I can see the icon in full.
