Linux logs off when I add PopupMenu items

[AlexTP]

Lazarus 2.3.0 (rev main-2_3-461-ge42dfcff56) FPC 3.2.1 x86_64-linux-gtk2

I saw several shutdowns (ie log-off's) of Xubuntu x64 here when I go to the PopupMenu designer in IDE,
and added few items. One shutdown was after I added 3-4 items, another one was after
I added single item, another one was after I added 2-3 items (just empty items in Obj Inspector).

I made new empty project, I added 2 PopupMenu instances, I dbl-clicked one of it,
I clicked PLUS icon in the Menu Designer, to add items in the first submenu.

I am not sure I want to install the latest IDE in 'main' on this PC.
maybe it was fixed in 'main'?
