Summary: idle in python 2.5c1 freezes on macos 10.3.9

Initial Comment:
Hi,

I installed python 2.5b3 on a powerbook ppc laptop
running macos 10.3.9 a few days ago.  python and idle
worked.  Now I installed 2.5c1.  python works fine from
a terminal.  When I start idle, it loads, puts up its
menu bar, opens a shell window, displays usual startup
info, and gives me a prompt.  But, I can't type or get
a cursor. Whenever I move the mouse over the idle
window or menu bar, I get a spinning color wheel and
can't do anything.

I deleted the whole /library/python tree, reinstalled
2.5c1, and exactly the same thing happened.

Oh, and I rebooted :)

Not sure what is happening, or how to diagnose.

I've created a new installer from the head of the release25-maint branch and 
that works correctly.

I'm keeping this issue open because I want to investigate why 2.5c1 doesn't 
work while the current head of the 2.5 branch does work.

Well, if there's anything I can do as a 10.3.9 user to test
this, let me know.  Too busy to delve into the python source
code though...

I can reproduce this on 10.3.9: IDLE starts and opens the interactive window, 
but then completely blocks (spinning cursor).

If I start IDLE from the commandline (/Applications/MacPython\ 2.5/
IDLE.app/Contents/MacOS/IDLE) I get a message about 'console' not being a 
valid command name. That requires further looking into, but is a red herring 
for this particular problem, removing the Tk-console hiding code in 
macosxSupport.py results in the same behaviour, without any further output 
on the console as well.

Upgrading aquatk to the latest version (8.4.10.0) on tcltkaqua.sf.net didn't 
help,  IDLE still hangs (Duh, that's because there's a /System/Library/
Frameworks/Tk.framework, which means a user install won't be used for 
IDLE).

The problem is also unrelated to my IDLE.app work, the same problem occurs 
when starting $prefix/lib/python2.5/idlelib/idle.py. 

According to gdb the IDLE process is handing in a semaphore call inside the 
Tcl mainloop. Time to get into serious debugging mode I guess :-(

BTW. IDLE does work correctly on a 10.4.7 system.

Maybe priority should be higher?  Hopefully Ronald has 
time to look at this; I don't have access to a Mac.
