Explorer Bugs: Explorer crashes right after started

(introduced November 2nd 2003)
This bug appered after adding MDI support to user32.dll. It appers because
before this commit no windows were opened and there were no buttons on
taskbar. I don't know what's the direct cause of this bug. For now the only
way to workaround this is to run explorer with parameter "-noexplorer".
Stack trace:

• DrawIconEx (called with invalid icon handle) - lib/user32/windows/icon.c
• create_bitmap_from_icon - subsys/system/explorer/taskbar/taskbar.cpp
