[python-win32] Puzzling Event Log entry

[Jorgensen, Jens]

This isn't really a problem. Note the actual API call for reporting an 
event:

BOOL ReportEvent(
  HANDLE hEventLog,    // handle to event log
  WORD wType,          // event type
  WORD wCategory,      // event category
  DWORD dwEventID,     // event identifier
  PSID lpUserSid,      // user security identifier
  WORD wNumStrings,    // number of strings to merge
  DWORD dwDataSize,    // size of binary data
  LPCTSTR *lpStrings,  // array of strings to merge
  LPVOID lpRawData     // binary data buffer
);


It's got a lot more than just a string. The call you are making likely 
just passes 255 for the dwEventID, which the event logging api expects 
to be an index to look up a message from and there's no message there. 
You can just ignore this--it doesn't mean that anything's wrong.
