This problem still persists on current 0.8.11-git build
with exactly same trace message.

Gnash: Gnash 0.8.11dev master-21707-b482bd6 with 80989fcd, dfba5258 and 4b3dae97 reverted.
Browser: iceweasel 3.0.6-3 from Debian main repository (no addons)
System: Debian GNU/Linux 5.0 Lenny on i386

This is a spin-off from bug #37008 (SoundCloud issue).

I've tried to call my test flash's method from JavaScript land,
using Flash 8-style ExternalInterface callback that's expected
to recieve the parameters "Hello" and "World" from JavaScript land,
and return "Too" back to the JavaScript land.

The ActionScript callback method was coded like this

The callback was invoked correctly under Adobe Flash Player (with proper security settings),
but doesn't under Gnash.

This is a trace output from Adobe Flash Player 11:

callee: load
callee: finished loading
status: load
status: finished loading
status: load
status: finished loading
callee: first run
callee: external initializing
callee: adding callback
callee: finished first run
callee: callback entered
callee: callback succeeded, expected (Hello,World) got (Hello,World)
callee: callback finished

You may see that the ActionScript callback function was invoked.

This is a trace output result from Gnash:

2929:1] 292 TRACE: callee: load
2929:1] 292 TRACE: callee: finished loading
2929:1] 292 TRACE: callee: first run
2929:1] 292 TRACE: callee: external initializing
2929:1] 293 TRACE: callee: adding callback
2929:1] 294 TRACE: callee: finished first run
2929:1] 384 TRACE: status: load
2929:1] 384 TRACE: status: finished loading
2929:1] 384 TRACE: status: load
2929:1] 384 TRACE: status: finished loading

You may see that the ActionScript callback was not invoked.
From JavaScript perspective, the call returns null.

Note that a group of lines like this appeared in the log every time that I tried to call this ExternalInterface callback
(The "121 bytes" part of the log was consistent; it's always 121)

2929:1] 2796 DEBUG: There are 121 bytes in the network buffer
2929:1] 2796 DEBUG: bool gnash::movie_root::processInvoke(gnash::ExternalInterface::invoke_t*) enter
