Issue affecting Android v2.3.5 Only

[mardawi]

An uncaught exception with following stack trace have occurred over 1,600 in the last month for an app using menudrawer. It only happens on 2.3.5 on Samsung S2 devices (such as GT-I9100 or GT-I9100T or GT-I9001). Any idea what is going on? Any suggestion for a workaround?

Not an issue with this library, the crash is in AbsListView.

The following patch fixes the issue. Tested on over 65k devices :)
