This is the exact version I am using. (lazarus SVN version may differ, but
it is the day before yesterday's SVN version)

They are the same as yours.
Maybe the bug is not in the menu editor, but in an installed package
and the menu editor is only the symptom?
Try uninstalling all unneeded packages. Does that change anything?
I created a minimal IDE without any additional packages installed ('make all').
Latest SVN. Revision 54848. (I did an svn update). FPC 3.0.2.
No defines are set when building the IDE
And I still get the error, I did as I outlined before. I waited 5 (five!)
seconds before clicking on the newly added item. That should eliminate
any possible timing issues.
I remind you that the LCL *warns* that something is wrong:
WARNING: TShadowItem.Destroy with LCLRefCount>0. Hint: Maybe the component is
processing an event?
This line alone should IMHO be enough to tell the IDE people that something
is actually going wrong.
Below is the output on the console when I do the steps as I outlined them
above.
I have reported it as a bug.
