Code block Splitting error(n=2)

[GoogleCodeExporter]

What steps will reproduce the problem?
Create simple text file with only a code block with a specific text. Or with a 
literal include of a file with the same text.
(See the attached document)

What is the expected output? What do you see instead?
I expect output and no crash log.

I get the following error:
Traceback (most recent call last):

Seems to be related to the string:
'Tommy Boy's Greatest Beats The First Fifteen Years nineteen eighty one to 
nineteen ninety six Disc three'

When I add another 'a' to 
the'testaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
' the string the error doesn't occur. It doesn't matter at what line this 
string is, as long as it is before the last. I suspect it has something to do 
with the line length.

* Version of rst2pdf? 0.91

* Version of reportlab? Standard version of 0.91

* Are you using wordaxe, and if true, what version? no

* Are you using rst2pdf with Sphinx, and if true, what version? no

I've seen the same error on some of my documentation, since I'm building pdf's 
with rst2pdf.

Is anyone going to fix this?

Roberto,

Let me know if you need any additional data or test-files.

Is the same error?

Any long string such as ``C:\Documents and Settings\<user name>\Application 
Data\Example\Example\<application version>\Security`` 

results in:

I have the same error here. It seems it is not related to the length of the 
sentence but to something else but I cannot figure out what's the problem in my 
file (it is quite long, and it appeared when I migrated from 0.16 to 0.92).

I am getting this all the time. Work around is to rearrange the vertical flow 
of the text. I believe this is because the troublesome page split will not 
happen any more at the middle of the code blocks (not sure if the terminology 
is correct - I mean the indented text after "::").

I just "fixed" an error of this kind in my document by inserting table of 
contents at the beginning of file. Sometimes I have inserted page breaks before 
the troubling code section. Sometimes I have splitted longer code blocks to 
smaller pieces. But it has happened sometimes that when I "fix" an error of 
this kidn, it pops up elsewhere in the document; especially if I have many code 
blocks and they are longer. This is big nuisance in the otherwise beautiful 
program!!!

I agree with you: it seems to happen for no reason. The problem is that in a 
long document it is not so easy to push the text to make this error disappear. 

It is also difficult to reproduce this bug because it needs a long document to 
make this appear. Have you any simple sample to submit to help devs reproduce 
the bug ?

Yes, this bug is what's blocking a rst2pdf release.
I can reproduce it allright (the rst2pdf manual itself fails), I just have not 
had enough time or luck debugging it :-(
