Can't add Drafts to Mailbox view

Question

Hi Guys,
Had my iPhone 5S a few days and I've come up with an issue in the Mail app, if I try to add "Drafts" to the Mailbox view at the top the app crashes, any other mailbox works, Trash, Junk, Sent etc but just not Drafts.
Anyone else experienced this, I've already had to reinstall iOS 7.0.1 as the handset went in to DFU mode on the first day from trying to upgrade to 7.0.1, would prefer not to do it.
Thanks,
Matt

Hi,
   I found the difference between the two dev systems.
   In the new system, check the table BSP_WD_EXT_HIST, set field BSP_APPL='ZBT115H_SLSO', there is no result. So the system suppose that the view is not enhanced, and will call the standard class.
   Set breakpoint in class CL_BSP_WD_ENHANCEMENT_API->CHECK_TARGET_CLASSES() and CL_BSP_WD_ENHANCEMENT_API->GET_CLASSES_FROM_EXT_HISTORY().
method GET_CLASSES_FROM_EXT_HISTORY .
   select single * from BSP_WD_EXT_HIST into ME->EXT_HISTORY
                   where BSP_APPL = ME->ENH_TARGET_BSP_APPL and
                         VIEWNAME = ME->VIEWNAME.
   if SY-SUBRC = 0.
     if ME->EXT_HISTORY-CUST_CONTROLLER is initial.
       raise NOT_DERIVED.
     else.
       CV_CONTROLLER_CLASS = ME->EXT_HISTORY-CUST_CONTROLLER.
       CV_CONTEXT_CLASS = ME->EXT_HISTORY-CUST_CONTEXT.
     endif.
   else.
     raise NOT_FOUND.
   endif.
endmethod.
ME->ENH_TARGET_BSP_APPL = 'ZBT115H_SLSO' and  ME->VIEWNAME = 'SOHOverView'
