+When opening a connection to a Sybase 12.5.1 database with the 
+SybaseClient provider, the following exception is thrown:

+in <0x00127> Mono.Data.Tds.Protocol.TdsComm:Store (int,byte)
+in <0x0004a> Mono.Data.Tds.Protocol.TdsComm:Append (byte)

+connection string parameter "PACKET SIZE" for SybaseClient. By default, 
+the buffer seems to be allocated with a size of 0.
