When using autocomplete in the console for a function description, and no description exists, the console shows the error:

Traceback (most recent call last):
File "/home/justin/blender-svn/install/linux2/2.55/scripts/op/console_python.py", line 229, in autocomplete
private=bpy.app.debug)
File "/home/justin/blender-svn/install/linux2/2.55/scripts/modules/console/intellisense.py", line 117, in expand

return matches, word, scrollback
UnboundLocalError: local variable 'scrollback' referenced before assignment

To reproduce, start blender, open console, type something like "bpy.data.armatures(" and hit Ctrl+Space. Clearly the problem is armatures is not callable, but this still needs fixed due to either someone not realizing it is not callable or if a description just doesn't have a description.
