Description of Problem:

After i upgraded my Monotouch version from 1.4.7 to the newer version 1.5, the
application deployed with success, but after running crashed without showing
any error. After debugging, i found that the crash was being caused when i set
the property SearchResultsDataSource of a UISearchDisplayController object to a
new object UITableViewDataSource.

In Monotouch's older versions, the application was working correctly.

Here it is a bit of the code that is causing the problem, that is located in my
constructor of my class TableViewController that extends UITableViewController:

"
this.searchDisplayController = new UISearchDisplayController(searchBar, this);

this.searchDisplayController.SearchResultsDataSource = new
GenericTableDataSource(this.tableDataSourceType,
GlobalApplicationConstants.TableViewAddMyCardsTypeWidth);
                this.searchDisplayController.SearchResultsDelegate =
this.TableView.Delegate;

this.searchDisplayController.Delegate = new SearchDisplayDelegate(
isFiltersAvailable, this.TableView, this.TableDataSource, cellHeight);          
"

class SearchDisplayDelegate : UISearchDisplayDelegate
class GenericTableDataSource : UITableViewDataSource


Steps to reproduce the problem:
1. Deploy the project that i refer in "Additional Information".
2. Run this Sample Project.
3. The app crashed before shows up in the emulator.


Actual Results:
The application crashed without showing any error message.

Expected Results:
The property SearchResultsDataSource of a UISearchDisplayController object
would be set successfully, without causing any crash.

How often does this happen? 
Always.

Additional Information:

This occurs too in the sample provided by Richard de Zwart in webpage
http://lsd.luminis.nl/building-iphone-applications-using-monotouch-part-4-the-uisearchdisplaycontroller/ 
That monotouch sample was working in Monotouch previous versions.
