Description
Description:
While testing Kitchensink, Base UI>Views>Scroll Views>Scrollable View w/o Clipping, I exited the test and the app crashed with signal 11. Please see attached crash log. This did not occur with KS 1.7.X built with SDK 1.7.5.
Steps to Reproduce:
1) Install KS from master build with 1.8.0
2) Navigate to Base UI>Views>Scroll Views>Scrollable View w/o Clipping
3) Click one of the tableviews
4) Scroll it up and down
5) Click "scroll views" button in the navBar while the tableview is in motion
Result:
App crash, signal 11
Expected:
Return to scroll views table
Note: Does not occur with 1.7.5

the applied fix / commit 49b3921266cbdf5eb40ecb581b4c57e7f74d118e / causes another crash. once i revert the commit, my app works fine again. both simulator and device. smells like one should check whether the proxy object exists and has the expected type.

Now that we have the application, we need reproduction steps. Please have someone on your team validate this against the master CI build to insure that it's still a valid bug. If so, reassign to me, otherwise close it.
Not able to reproduce with latest Master CI build 1.8.0.1.v20111123202050
