        <pre>Description:
A crash occurs while dragging a button over a "frozen" spreadsheet row under
certain circumstances.

This happens every time with the attached spreadsheet ("crash.ods"), if a
(unrelated) group of buttons is first un-grouped.  Somehow the act of
un-grouping the group makes a later button-drag crash.   FWIW, the group is a
compound group created by grouping a row of buttons, then selecting that group
and another button and grouping the combination.

The demo was derived from a production spreadsheet developed using earlier LO
versions, so the crash might be due to backwards-compatibility issues (just
guessing).

Steps to Reproduce:
1. Open attached spreadsheet "crash.ods" (Disable macros if prompted)
2. View->Toolbars->Form Design: Checked
3. In the floating Form Design toolbar, 
     click the icon to enter Design Mode 
4. Click in the YELLOW button, to select the large group
5. Rightclick->Group->Ungroup
6. Click somewhere else (de-selects the buttons)
7. Drag the GREEN button down towards the large group
(crash occurs when it passes the frozen row)


Actual Results:
Crash

Expected Results:
No crash


Reproducible: Always


User Profile Reset: No
