It looks like the powerof(0) problem derives from one of your channel drivers. 
I found that the following solved the problem with my chan_capi:

1)

Use "ast_set_read_format()" and "ast_set_write_format()" to initialize the 
format used, hence "chan->lastreadformat" was uninitialized.

     fmt = ast_best_codec(fmt);
 
+    ast_set_read_format(pbx_chan, fmt);
+    ast_set_write_format(pbx_chan, fmt);
+


2)

In my bridge routine, I only forward "AST_FRAME_VOICE" now.

But still I think asterisk has a bug, in that it cannot handle  
"AST_FRAME_NULL", hence "f->subclass == 0", and it is forwarded by  
"ast_write()" to "ast_translate_write()", which causes a powerof(0) error 
with Asterisk 1.2.12+.
