PR# 12612 Moving Project toolbar to top row and clicking Toolbar Options caused crash

This problem is not currently reproducible.  I moved the Project toolbar to the
top row (Standard buttons) and then clicked on Toolbar Options button.  I tried
to reproduce it but so far could not.  Perhaps the exact position to which
I moved the Project toolbar is important.  Trace attached.

I think something fixed this - either a newer version GTK+ or a change to
Vision2 or docking library.  I cannot reproduce it on OpenSolaris 2008.05.
The bug was a seg fault in {SD_TOOL_BAR_DRAWER_IMP}.draw_item.  If I ever
see it again, I will re-report it.

Closing report.

I just reproduced it on rev 68703, Solaris 10 on x86 (32-bit).  You might have
to add and remove Feature address as well as feature label. I have also 
encountered this crash numerous times when moving toolbars around.  I hope you
can find a way to reproduce it, because it is definitely still present.

Actually, I think I just now discovered the critical factor in reproducing this
bug.  As soon as you click the OK button to finish customizing the toolbar and
accept the new toolbar layout, immediately move the mouse up to the Address
toolbar row.  You might need to move the mouse within that row as well.
When I do this, it increases my odds of encountering the problem.

I have also noticed that sometimes after I customize the Project toolbar, clicking
on the Toolbar Options button displays the little popup window with the
non-visible choices over by the left side of the main window, very far from
where the Toolbar Options button is.  I don't know whether this is related to
the problem.

I can't reproduce this on Solaris 10 x86 32bits (installed on VMware). My GTK version is 2.4.9. You can see attached the reproducing video. I added the feature label, then remove the feature label several times. Eiffel Studio works fine.

Attached is a 7 zip compressed format. I can't use zip format since the compressed format will be very big (15M). You can download 7 zip here: http://www.7-zip.org/ I don't know whether 7 zip works fine on Unix systems. Sorry.

The video is AVI format.

I believe this may be the same as bug #12756.  

This can now be reproduced as follows:

Open project which is sample graphical application.
Click on Toolbar Options of Address toolbar and select Customize.
Click on Feature Label item and click Remove.  Click OK.
Click on Toolbar Options of Address toolbar and select Customize.
Click on Feature Label item and click Add.  Click OK.
Usually repeating this a sequence of removing Feature Label from Address toolbar
   and then adding it back once or twice will cause a crash with the previously
   attached trace.
