Tab bar does not appear in Mac OS X Fullscreen mode
When switching from windowed to fullscreen mode occasionally the tab bar disappears in fullscreen mode and appears again when switching back to windowed mode using Apple-Enter, and disappears again when hitting Apple-Enter again.
Normally I see the tab bar all the time. The preference 'Hide tab bar with only 1 tab' is enabled, but disabling this option does not change the behaviour.
This happens only occasionally. Normally the tab bar is present, hence I think it is a bug and iterm gets its knickers in a twist somehow.
