I'm getting a reproducible core dump in ibuild-beta.
I'm trying to build the "Sted" example from the Ibuild User's Guide. In trying
to relate the Up/DownMovers to the FileBrowser I consistently get ibuild to
core dump.
The setup I've got is roughly the following:
I build a Filebrowser with a vertical scroller on the right side.
The UpMover, VerticalScroller, and DownMover are composed in a VBox.
The Filebrowser is then composed in a HBox with the scroller VBox.
This was all wrapped in a Dialog Subclass.
Using Examine I changed the Dialog subclass "class name" to "Foo".
I then examined the Filebrowser and tried to change the following:
Member name: browser
Buttonstate: browserbs
Member function: browserselected
Making any of these three changes, individually or together, results in a core
dump when the "OK" button is selected.
The reason I want to make those changes is so I can set the "instance adjusted"
field in the Up/DownMovers to "browser". This is the way things appear to be
done in the dialog box for alpha doc, which is the only good ibuild application
I've found to use as a model.
Any help will be greatly appreciated.

The destructor of BooleanStateVarView deletes the buttonstate which has been destroyed by the checkbox causing ibuild to crash after either the stringbrowser's and filebrowser's info dialog box is removed. The following patch solves the problem.
