[openbox] Alt-Tab,Tab crash

[Alexey Korop]

Hi, All!

    I get the snapshot of the latest state of the "master" branch 
(http://git.icculus.org/?p=mikachu/openbox.git;a=snapshot;h=50d662681160c309ea86268c0d05794b87b75593) 
an compile it. This version crash after Alt-Tab,Tab (if one or more 
window exists).
    The previous version 
(http://git.icculus.org/?p=mikachu/openbox.git;a=snapshot;h=8ada991d829671ab5e6dd4c5526b6a0238ba6a16) 
not crash, but display the Alt-Tab dialog horizontally that is strange 
for the 3.999.
