What?  How did you possibly read that from what I said?

The code that you wrote has a bug.  There is nothing wrong with GTK or GTKMM, you're just using it wrong.

You are creating a secondary worker thread.  In that worker thread you are accessing a GUI widget.  You can't 
do that.  Not being able to do that is not a bug; trying to do it anyway is.

So far everyone has been saying the same thing, just phrased differently.  It appears however that you have 
not yet understood any of those suggestions.

I even explicitly told you what you should be doing instead (using a queue with a mutex and a Dispatcher), 
which is the same thing that Andrew Potter suggested that you try last week (with a code example, no less).

No, that is not what I was suggesting.  I was saying that you should first learn how multithreading works in 
general.  Then how multithreading works in GTK+/GTKMM (since the two are basically the same thing, just with 
different syntactic sugar).  And only then try to apply it to your application.
