IDLE crash when i type the character ^ (for example writing "ê" in a comment).

I have the crash only on Mac OS X (Mac OS X 64-bit/32-bit Installer (3.2.3) for Mac OS X 10.6 and 10.7).

I don't have this crash on Linux.

Please run IDLE from the command line and send the output when it crashes. (If I knew Mac better I would tell you the precise instructions)

Do you have a recent version of ActiveState's Tcl/Tk distribution installed?  

If you do not have this installed you ran into a known issue in Apple's copy of Tcl/Tk, see <> for more information.

My system is an up to date OS X 10.7.
The Tcl/Tk package is the default (I haven't installed a specific version).
Should i need to install the ActiveState package ?

Yes. As the webpage I mentioned describes Apple's installation of Tcl/Tk contains a number of serious bugs, one of which is that Tk's handling of dead keys (the "^" you use write "û") causes crashes.

To get a fully functional copy of Idle you'll have to install ActiveState's Tcl/Tk as well. 

We could ship a copy of Tk in the installer as well, but have chosen not to do that because the installer is large enough as it is. Furthermore the Cocoa port of Tcl/Tk is at this time still a moving target,  which means that we couldn't even ship the same version of Tcl/Tk for the entire lifetime of Python 3.2.x.

Please let us know if installing ActiveState's Tcl/Tk fixes the crash, I expect it will but you might have run into yet another Tk bug.

Installing ActiveState's Tcl/Tk package fix the crash.
Thank you for your answers.
