Looking at the conf file parsing lib (common/miscutil/conffile.h)

/* LENGTHS                                                                      
                                                                                
                                              
 *                                                                              
                                                                                
                                              
 * The following are the maximum values and lengths throughout                  
                                                                                
                                              
 * the conffile parser.

#define CONFFILE_MAX_LINELEN                  32778
#define CONFFILE_MAX_OPTIONNAMELEN              256
#define CONFFILE_MAX_ARGS                        64
#define CONFFILE_MAX_ARGLEN                     512
#define CONFFILE_MAX_ERRMSGLEN                 1024

A jump from 512 to 1024 would probably fix this.  You could try this as
a quick fix and recompile.
