The pointer returned by g_mime_utils_header_decode_text is from the
following line in rfc2047_decode_tokens
return g_string_free (decoded, FALSE);
The docs for g_string_free say
Frees the memory allocated for the GString. If free_segment is TRUE
it also frees the character data. If it's FALSE, the caller gains
ownership of the buffer and must free it after use with g_free().

Apparently as of GMime 2.4, you don't need to call
internet_address_list_destroy anymore, but you still need to call
g_object_unref (from the GMime Changelog).
On the medium performance corpus, valgrind shows "possibly lost"
leakage in "notmuch new" dropping from 7M to 300k.

There is still some problem left: in the contex one can see the following
calls:
g_hash_table_insert (message->headers, header, decoded_value);
and then
combined_header = xmalloc(hdrsofar + newhdr + 2);
strncpy(combined_header,header_sofar,hdrsofar);
*(combined_header+hdrsofar) = ' ';
strncpy(combined_header+hdrsofar+1,decoded_value,newhdr+1);
g_free (decoded_value);
g_hash_table_insert (message->headers, header, combined_header);
Now, decoded_value should always be freed with g_free() and combined_header
with free(), note also that the hash table is initialized with:
message->headers = g_hash_table_new_full (strcase_hash,
strcase_equal,
free,
free);
i.e. finally the allocated string is freed with free() (in case
we're freeing... I did not look so far...).
Maybe all allocations and frees in the values of this header hash table
should be converted to use g_ -functions ? (or start to use talloc contex
there)
