compiz crashed with SIGSEGV in CompWindow::id()

[Anders Kaseorg]

Binary package hint: compiz

This happens every time I start gitk. It’s 100% reproducible, even under a freshly created account, and makes it completely impossible to run gitk under compiz (the window doesn’t even show up after the crash).
