[Mono-winforms-list] Bug? DataGridView on Mono Crashes (or locks rather)... does not occur on Microsoft platforms

I appear to have found a bug in the mono stack? Or was it a design implementation choice?
Here is the scenario... I pull data from a database, then load up a Dataset then find it to a Datagridview. Then I substitute textual values inside of that grid based on the numeric values in the grid. I do this "after" I have already bound the DataSet table to the DataGridView.
On the Microsoft side (Vista) this error does not occur... or no lock up. The DataTable "object" the datagridview is bound to simply updates to the underlying table data changed on the fly. When you run the commented lines of code the application on Mono will lock up and just stop execution. I get no exception thrown or any clue as to what is going on. The app just locks, I have to manually kill the process. I changed the code just to update the grid cell directly and it works fine on both platforms for display purposes.
// Commented code that locks on linux
// Uncommented code below runs on both mono and the Microsoft stack no problems as expected
Version information for reproduction
OpenSuse 11.1 32-bit Linux, Mono 2.2 (freshly released and installed)
Microsoft Windows Vista Home Premium edition 32-bit, .NET 2.0 framework compilation for all libs
1 - Pull db data
2 - Bind to DataGridView
3 - Update numeric values in the underlying bound DataTable bound to the Grid (originally via the DataTable, now just the Grid Display Cell value)
