first time I hear of this (or see this myself, and I use git gui every day on Mac OS X); in part this may be due to the fact that many of the menu shortcuts assigned by git gui conflict with existing OS X shortcuts and don't work anyway e.g. cmd-A (esp if a text widget is in focus)...
personally I would hate for my git gui to be downgraded to Tk 8.4 and Carbon because of this small issue, and I'm unlikely to be alone.

this is intentional and triggered by the use of ttk, there is a config setting to turn it off (gui.usettk)

please don't brute-force around the problem in this way, there are many features that the Cocoa Tk in 8.5+ adds that would be lost by such a change.
Moreover the fact that 8.4 is present in that location is for backwards compatibility only, please don't introduce any new dependencies on it.
An effective small workaround for the problem appears to be to turn off the menu accelerators for the affected commands (the key shortcuts will still work, since the actual key bindings are independent of the menu accelerators), see below.
Is there a complete list of menu shortcuts that bring up a dialog?
Ultimately the right way to address this issue is to fix it in Tk, please report this in the Tk bug tracker if you haven't already, a quick glance in the debugger shows a hang in recursive event loop invocation such as used by tk_dialog when called from a menu accelerator callback.
Thanks!
Cheers,
Daniel
