Can't scroll on MyPaint's Brush Widget

[Otto Robba]

I can't scroll using the scrollbar on the "Change Brush" widget on MyPaint.
It shows the overlay scrollbar but clicking it has no effect. Tried to click, to drag, etc... nothing.
It is still possible to scroll using the mouse wheel.

I'm running an updated version of Ubuntu 12.04. This issue does not happen on Arch with Gnome 3.4.2 thus is must be something with Ayatana or the patched GTK (there are other Ubuntu-specific Mypaint bugs).

Tried on two different computers:

Tablet PC T4420, Fujitsu. 2.53ghz core2duo, 4 gb ram, intel 4500 gma.

The other is a tower pc with a quad core, core2duo gen. processor. 4gb ram, Radeon 4850.

I have the identical problem. Can't drag the scrollbar in mypaint. Acer Aspire One laptop, Ubuntu 12.04, have to turn on the mouse and use the scrollwheel.

Same problem here, also on Ubuntu 12.04 which says I'm running the latest version available (repositories) and it's now 2013... still not fixed? Not a good workflow having to drop my wacom and pick up a mouse any time I want to change a brush.
