I just checked it by adding a printf() to gdb/generic/gdbtk-hooks.c
in gdbtk_post_add_symbol() and you are right it appears that this method
is not called.
Filling of the filename combobox appears to be broken since gdb 5.1 for me.
I can remember it worked with 5.0 but no longer since then. So I made my
"solution" I posted here last week. (which is not a real solution just a
workaround if there is another mechanism which should take care about this.)
