Leaf-menu not list, sorry.

[HaikuBot]

100% reproducible:

1. Move Deskbar as a bar along the upper or lower border.
2. Double Click on Leaf Menu and you ger crash.

[anevilyak]

I think I even remember this one being reported (but never fixed) back in the days of OpenTracker...

[damoklas]

I'm check, on BeOS Deskbar v5.2.1 is OK.

[damoklas]

Haiku rev. 35546, Deskbar still crash.

[streak]

Any progress since? Deskbar still crashing in #35878 :/

[darkwyrm]

Clicking slowly on the leaf button does not cause the crash. The crash is caused by a NULL pointer reference on item in the double-click-related code at the bottom of MouseDown. Attaching a patch until I get commit access squared away.

Thanks, fixed in hrev36389.
