I keep on getting messages like this:

16:25:35 [fecaen,ERROR] [odb.c:4567:db_get_data,ERROR] data for key
"/DAQ/params/VX1730/custom/Board 0/Channel 0/Input range" truncated

whenever I start my frontend. Input range is defined to be a BOOL and using
odbedit to read it shows:

Key name                        Type    #Val  Size  Last Opn Mode Value
---------------------------------------------------------------------------
Input range                     BOOL    1     4     75h  0   RWD  y

without any error message. The entry is read using

         size = sizeof(fInputRange);
         db_get_data(hDb, hSubKey, &fInputRange, &size, TID_BOOL);

where fInputRange is a bool.

Where does this message come from and how can I resolve this?
