BeatBox crashes after trying to open Preferences dialog

[Adolfo Jayme Barrientos]

Using beatbox version 0.7+r797-0~quantal1, I can't open the Preferences dialog.

While running the program from terminal, it gives the following error:

ERROR:/build/buildd/beatbox-0.7+r797/obj-i686-linux-gnu/core/PluginManager.c:1130:beat_box_plugins_manager_get_view: assertion failed: (bottom_box != null)

Same here on Quantal 64bit. Here's the full output:
