           Summary: Successive try/catch fails to trap errors on device
    Classification: Mono
           Product: MonoTouch
           Version: unspecified
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Critical
          Priority: P5 - None
         Component: Runtime
        AssignedTo: gnorton at novell.com
        ReportedBy: gcarrier at gmail.com

AppleWebKit/531.9 (KHTML, like Gecko) Version/4.0.3 Safari/531.9

This code causes the program to terminate when on the device (when freshly
loaded, so there are no variables stored), but works fine on the simulator:
-------
try {memField2.Text = memField1.Text =
NSUserDefaults.StandardUserDefaults.StringForKey("MemoryTotal");}catch{}

try     {unitPrice.Text =
NSUserDefaults.StandardUserDefaults.StringForKey("unitPrice");}catch{}

-------
commenting out either line works fine on the device.  Personally, I think the
try/catch should never result in blowing up unless the catch causes a blowup. 
i.e. regardless of what I may be doing wrong in text and variable handling
within the try statement.

If I don't retrieve any settings, but do store them: These retrieval lines
(about a dozen) work fine, retrieving and setting my variables.  The variables
I am setting are the text properties of UITextFields, but I also have a few
other UI objects I manipulate seemingly fine on the simulator.
