Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

python mode auto indentation has been broken for me for some time.
I tried again today and it works better, but not much.

I tried using emacs -nw -q and the little python program below.

the problem is  especially obvious on the line marked #1, or #2
Try moving the indentation to column 0. Emacs will say "sole
indentation". 

I'm expecting indentation to go 4 spaces in under the "for" or the
"if" statement.

#!/usr/bin/python
import os

loop=0
missingfiles=0
for filenum in range(1,471):
    filename="%03d.pgm"%filenum #1
#print(filename)
    if not os.access(filename,os.F_OK):
    missingfiles=missingfiles+1
    print "%s "%filename ,
    loop=loop+1
    if loop==20:
       loop=0 #2
       print 
print
print "missing files:%d"%missingfiles

I had a look at python.el, and at line 510 there is code like:
		      (or (cond ((python-open-block-statement-p t)
				 python-indent)

I would expect (python-open-block-statement-p t) to return t, and the
indentation to occur, but it returns nil. However, I have no idea how
this code is supposed to work, so take this with a grain of salt.

If emacs crashed, and you have the emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/local/share/emacs/22.0.51/etc/DEBUG for instructions.
