Crash log

Triggered using AXE3 (hex editor):
http://advanced-hex-editor-a-x-e.en.softonic.com/
Crashes on program start, after "evaluation period expired" warning and before
displaying the main window. Does not happen systematically, but with a high
probability (~8 out of 10 runs). See attachment for error details.

This is a regression. Looking at the short change history of
dlls/comctl32/treeview.c I identified the commit introducing the regression as
95a15a3482ba47c1b84fd77a63f95d5cd784a97a , and re-introducing a "return FALSE"
in the "if (!TREEVIEW_ValidItem(infoPtr, item))" code branch indeed cures the
crash.
