Introspect error: No reply within specified time

[Luigi Paioro]

Hello!

I've create a service which creates a bus name (e.g. "my.example") and 
puts on it a persistent object (e.g. "/my/example/Hello"). The 
persistent object exports a method which returns a string (e.g. 
getName()). (python code)

Then I've created a client application which connects to that bus and 
object with the suitable interface and it simply calls the getName() 
method and prints the returned value (I can do it even through the 
python console).

Well, everything seems to work, but when I call for the first time the 
method (just after the bus and the object are created by the service), 
after few seconds waiting (!!!) I get this error: "Introspect error: No 
reply within specified time"; just after that I receive the method 
result. If I call the method again and again it is fast and returns the 
output value without errors.

Do you have an idea about what could be the problem?

Thanks in advance.

Luigi
