Pasting into iPython does not work as expected

Required information!
OS version: Win7 x64
ConEmu version: 120604 32bit (32-bit because I'm using 32-bit Python)
Far version: N/A

*Bug description*
Pasting long (> ~250 chars) blocks of text into iPython doesn't work as expected

*Steps to reproduction*
1. Start new iPython console or attach to running iPython console
2. Copy example text from web browser, text editor etc. (DOS/ANSI, UNIX/UTF8... makes
no difference how the text is encoded)
3. Paste into iPython window using '%cpaste' magic command

Observed behavior: Several lines of text will paste with appropriate CR and indentation.
However, at some random point, the block will either stop, or will jump ahead a random
number of lines (characters, maybe?). It is so flaky that I have actually seen it work
properly >_< (once)

Expected behavior: Pasting "properly" formatted python code (where "proper" is defined
as: line ending markers of some kind separate lines, and indentation using tabs or
spaces is as expected for python code. The ipython "magic" command '%cpaste' will strip
out extra characters from line beginnings (e.g. if pasting from an email, removes '>>')
and "do the right thing" with line ending markers.

Several questions...

What version of iPython you are using?
I try to install 0.12.1 and get setup error:
*** run_installscript: internal error 0xFFFFFFFF ***

Trying to start (file however appears) get an error:
C:\Python24\Scripts>ipython.exe                             
Traceback (most recent call last):                          
  File "C:\Python24\Scripts\ipython-script.py", line 5, in ?
    from pkg_resources import load_entry_point              
ImportError: No module named pkg_resources                  

Where to get sample script for pasting? :)

Sorry, I should have thought of that. Python 2.6.6 32-bit, iPython 0.12.1
I always install using pip. 2.6 is the oldest I've used: maybe there's some incompatibility
with 2.4.
Here's a standalone piece of code you can try (I'd suggest trying it several times;
it actually worked for me just now after failing :) ). Input %cpaste', then paste the
code, then input '--' and ENTER. If it pastes without error, you should be able to
do "subStringMatchExact('atgacatgcacaagtatgcat', 'atg')" and get "(0, 5, 15)" as a
result.
-----------------------------------------------------------------
def subStringMatchExact(target_string, key_string):
    """Return a tuple of indices of the key string in the target
    string.

    """

    i = 0
    index_list = []

    if key_string:
        while i < len(target_string):
            i = target_string.find(key_string, i)
            if i == -1:
                return tuple(index_list)
            else:
                index_list.append(i)
            i += len(key_string)
    return tuple(index_list)

Excellent! I haven't done a *lot* of testing, but the two examples I tried (40 lines
and 37 lines) both worked perfectly the first time. Pasting was a /little/ slow, but
hey, it works :)

The pasting was rewritten and the code has become too fast :)
Small lags have been added in order to avoid input queue overflow.
In future may be...
