Lazarus Crash in IDE Docking Mode

Description:

Today I tried the IDE Docking Layout:

  1. Lazarus v2 RC1 32bit on Win10 64bit.
    (other systems (I can't test) probably have the same problem)

  2. IDE docking-layout (anchordockingdsgn.lpk installed)
    (IDE nondocking (floating) layout doesn't cause the crash)

  3. IDE two-column docking-layout:
    Left column: Object inspector
    Right column: Source editor at top and Pagecontrol at bottom.
    The Pagecontrol contains as tabsheets:
    Messages, Search Results and all (9) Debug Windows.
    Code Explorer is not visible (has been closed with its red button).

  4. The loaded project is a new application (empty form)
    (This might be irrelevant.)

  5. When I click "View / Code Explorer"
    ( only Code Explorer is causing the crash, other IDE Windows are OK).
    then the IDE is jumping/flickering wild on screen, many times per second.
    After some seconds Lazarus becomes invisible, except for its Pagecontrol,
    and a modal message appears: "Access violation".
    Clicking on this message closes the IDE after another few seconds.

In summary, Code Explorer can't be used together with this IDE Layout.
