The "No symbol table info available" means that gdb couldn't find debug symbols for that function. It seems that you are either lacking debug symbols for both glib and gtk, or that gdb just can't find them. If it isn't the first one, I don't know how to solve the second one.
For the record, as this is a keyboard-related issue, were you running ibus?
