When I try to run IDLE in Py30b3 I get a traceback, then the main window
appears with an error message box and an OK button; once I click OK,
IDLE goes away.

$ ~/opt/python30b3/bin/idle
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/mark/opt/python30b3/lib/python3.0/idlelib/", line
76, in main
AttributeError: 'Thread' object has no attribute 'set_daemon'

It looks like there's been some mixup with threading... in an earlier
beta there was setDaemon(), then it became set_daemon(), and now it is
back to setDaemon() again. And unfortunately, the obvious fix (change
the name to setDaemon()), although it gets past this problem, just leads
to another:

$ ~/opt/python30b3/bin/idle # using setDaemon
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/mark/opt/python30b3/lib/python3.0/idlelib/", line
76, in main
  File "/home/mark/opt/python30b3/lib/python3.0/", line 674,
in setDaemon
    "Thread.daemon property", DeprecationWarning)
  File "/home/mark/opt/python30b3/lib/python3.0/", line 18,
in showwarning
    file.write(formatwarning(message, category, filename, lineno, line))
TypeError: idle_formatwarning_subproc() takes exactly 4 positional
arguments (5 given)

I did run make test and got 300 tests OK with 22 skipped all expected on

Just realised how to fix this. Change line 76 in idlelib/

# change this:
# to this:
    sockthread.daemon = True

and IDLE runs fine.

This should be changed in 2.6 as well (from sockthread.setDaemon(True) to 
sockthread.daemon = True).

By the way, I notice that there are also used of setDaemon, isDaemon, 
getName and setName in Lib/multiprocessing/dummy/;  these 
should probably also be replaced.
