boa-constructor 0.2.8 (Debian package)
* libwxgtk2.4-python 2.4.2.4
* python 2.3.x

If I press:

-> New -> wxApp
-> FrameDesigner
-> Containers/Layout
-> wxToolbar

I create a toolbar of any size. Then

Buttons -> wxButton

Just clicking on the tool-bar causes the program to fail.

    Hi Cdric,

    PS, you're not really supposed to add wxButtons to the
    toolbar (normally toolbuttons are added via the collection
    editor's New button), but it shouldn't crash either.

    Can you please investigate this a little further?

    I'd like to know if it's a wxGTK issue or a Boa issue.

    Run Boa with the command-line parameter -T to create a
    trace file of the program execution up to the point of the
    crash.

    Please report what the last few lines of the Boa.trace file
    reveals.

    Thanks,
    Riaan.

    Hi Cdric,

    Nothing suspicious (like unterminated functions) in the Boa
    trace file as far as I can see. This usually means that the
    crash happened from an event processed after the normal
    code ran to completion.

    In the GDB stack trace it look like something bad happened
    while updating a wxTreeCtrl (possibly the Objs tree in the
    Inspector). I've got no ideas as to why though.

    I'll have a look into this next time I fire up my Linux system.

    Thanks for the efforts,
    Riaan.
