bitbake/exceptions: Handle reports from the field of exception code failures
PATCH 1/1 bitbake/exceptions: Handle reports from the field of exception code failures
Despite using python 2.6, there have been reports of issues where bitbake is printing tracebacks with errors in the exception handling code. This was masking the real error.
Since we need to do whatever we can to give the user good feedback about errors, detect the tuple instead of namedtuple case and don't fault in the exception handler but just give up trying to traceback any further.
In the reported cases, this gives a message the user can then understand.
