send_with_block_and_reply fail

[Johan FISCHER]

hi,

I'm developping a client connecting a server using the dbus lib with the server
function using the Glib binding.
The client is using only dbus_send_with_reply_and_block function but sometimes,
It seems the server send the reply too fast and the client miss it and timeout.

Anyway, this is the output with DBUS_VERBOSE:

So, it seems the client receive a reply message serial 32, insert it in the
incoming queue, delete it (no filter installed) and then the
dbus_send_with_rpely_and_block start listening for the reply.

Any idea ?

Thx.
