This procedure adds a textdomain to the list of domains Gimp searches 
for strings when translating its menu entries. There is no need to 
call this function for plug-ins that have their strings included in 
the 'gimp-std-plugins' domain as that is used by default. If the compiled 
message catalog is not in the standard location, you may specify an 
absolute path to another location. This procedure can only be called 
in the query function of a plug-in and it has to be called before any
procedure is installed.

This procedure changes the way that errors in procedure calls are
handled. By default GIMP will raise an error dialog if a procedure
call made by a plug-in fails. Using this procedure the plug-in can
change this behavior. If the error handler is set to
%GIMP_PDB_ERROR_HANDLER_PLUGIN, then the plug-in is responsible for
calling gimp_get_pdb_error() and handling the error whenever one if
its procedure calls fails. It can do this by displaying the error
message or by forwarding it in its own return values.
