It looks like the contacts between the banana and the table may be unstable. You can inspect them by choosing View -> Transparent and View -> Contacts.

One solution would be to tweak the surface parameters of the banana's collision. Something like this:

    <surface>
<friction>
<ode>
<mu>0.5</mu>
</ode>
</friction>
<contact>
<ode>
<min_depth>0.001</min_depth>
<kp>1e9</kp>
</ode>
</contact>
</surface>
