I came across this bug while using regedit.

Steps to reproduce:
1) Create a new wineprefix
2) wine regedit
3) In the left-side window select a registry key/hive (e.g. HKEY_CLASSES_ROOT).
4) In the right-side window place the mouse pointer somewhere below the last
row (in the empty/white area). While left-mouse button is pressed, drag the
mouse upwards (as if you were selecting multiple rows). When the mouse cursor
reaches the last row Wine crashes.

This is due to the following commit:

The patch can be reverted cleanly on 1.3.23 and that fixed the crash.

Author of the patch added to CC.
