Is there tool to watch GTK signals?

["Andrew E. Makeev" <andrew solvo ru>]

I will try to explain my problem.

I have application written in gtkmm2. (RH9, last GTK/MM packages.)

I am trying to configure number of entry widgets added to TextView. 
Every time I have to create new TextBuffer, and add new entry widgets. 
Since I have lotsa user data associated with entry widgets, I am storing 
pointers to them in std::map, so, before creating new TextBuffer, I am 
clearing map and deleting entries. Then I am creating new entries and 
setting values to them.

The problem is when I am calling (*some_entry)->set_text () function, 
just in that time signal destroy called occasionally on that entry. So, 
next operation (on that entry) crashes application.

Any help will be appreciated.
