When attempting to call SQLiteDataReader.GetValue(int) on a column whose data type is "date" and its value is not a valid DateTime value, en exception is thrown:
A first chance exception of type 'System.FormatException' occurred in mscorlib.dll
Additional information: String was not recognized as a valid DateTime.

Expected result: since the generic object GetValue(int) function is called, it must return whatever value is contained in the column.

Environment: Win 7 64 bit En
System.Data.SQLite.dll 1.0.91 (x86)
SQLite.Interop.dll 1.0.91 (x86)

Steps to reproduce:

create table bug(f1 date);
insert into bug values("hello");

IDataReader rdr = open_data_reader_somehow;
var value = rdr.GetValue(0); // fails
var date = rdr.GetDateTime(0); // fails - as expected in this case
var str = rdr.GetString(0); // works - strangely enough - given that the GetValue fails

The GetString method should be used to read values that do not conform to their
associated type affinity.  The behavior of GetValue is correct.
