asterisk users - Nov 2009 - Warning: __ast_register_translator: plc_samples 160 format f/__ast_string_field_init: trying to reset empty pool

In a (futile?) attempt to get rid of warnings, I have this:
[Nov 30 10:39:49] NOTICE[68467]: loader.c:937 load_modules: 149 modules 
will be loaded.
[Nov 30 10:39:49] WARNING[68467]: utils.c:1427 __ast_string_field_init:

(5 times more)
SIP channel loading...
(5 lines of AEL loading)

'/usr/local/etc/asterisk/extensions.ael'.
[Nov 30 10:39:49] WARNING[68467]: translate.c:641

[Nov 30 10:39:49] NOTICE[68467]: config.c:1923 
ast_config_engine_register: Registered Config Engine curl

Googling these two warnings give nothing usable (for me...)
