[Lazarus] Error when installing project groups

[Michael Van Canneyt]

Hi,

I tried to install the lazprojectgroups package.

Upon the next start of lazarus, the whole of lazarus crashes with an index
out of bounds. I believe someone else reported it already.

The strange thing is that the crash happens in something unrelated to lazprojectgroups:

[FORMS.PP] ExceptionOccurred
   Sender=EListError
   Exception=List index (24) out of bounds

Presumably, both packages register a menu section.

The lines in question are

         if ContainerMenuIndex>ContainerMenuItem.Count then begin
           debugln('TIDEMenuSection.UpdateMenuStructure CREATE BottomSeparator Name="',Name,'" ContainerMenuIndex=',dbgs(ContainerMenuIndex),' ContainerMenuItem.Count=',dbgs(ContainerMenuItem.Count
           GetRoot.WriteDebugReport(' Bottom ',true);
         end;
         ContainerMenuItem.Insert(ContainerMenuIndex,FBottomSeparator);
       end;

At the very least the

        if ContainerMenuIndex>ContainerMenuItem.Count then begin
           debugln('TIDEMenuSection.UpdateMenuStructure CREATE BottomSeparator Name="',Name,'" ContainerMenuIndex=',dbgs(ContainerMenuIndex),' ContainerMenuItem.Count=',dbgs(ContainerMenuItem.Count
           GetRoot.WriteDebugReport(' Bottom ',true);
         end;

Looks strange, since if that happens, there is sure to be a crash with the
insert, but no action other than a debug message is posted ?

What can I do to prevent this and yet have both packages installed?

Michael.
