That does not work either. I also tried the code

%Exception std::exception(SIP_Exception) /PyName=StdException/
{
%TypeHeaderCode
#include <exception>
%End
%RaiseCode
     const char *detail = sipExceptionRef.what();
     SIP_BLOCK_THREADS
     PyErr_SetString(sipException_std_exception, detail);
     SIP_UNBLOCK_THREADS
%End
};

from the SIP reference guide. I still get a crash.
And I can not find any try/catch blocks in the generated cpp files.

My sip file begins as follows:

----------------------------------------------------------------------

%Module TextTable 0

%Include TypeMaps.sip

%Exception std::exception(SIP_Exception) /Default/
{
%TypeHeaderCode
#    include "../../Common.h"
#    include "../../TextTable/Exceptions.h"
%End
%RaiseCode
      SIP_BLOCK_THREADS
      translate(sipExceptionRef)
      SIP_UNBLOCK_THREADS
%End
};

class TextRow {

%TypeHeaderCode
#	include "../../Common.h"
#	include "../../TextTable/TextRow.h"
%End

public:
	TextRow(const TextRow& other);
	~TextRow();

...
