Here's what the backtrace says :

Python\n#+STARTUP: overview (others are showall)\n#+STARTUP:
hidestars\n#+OPTIONS: toc:nil\n\n* Introduction\n\n** Mathematical
understanding of regular expressions\n\n\n** regular expressions and
Operations\n - sequencing :: by default\n - grouping :: [abc] one of any
characters in the group\n - alternation :: |\n - repetition :: a* and a+
and a?\n - complementation :: ^\n\n\n\n** From strings to Regular
expressions in Python ::\n Using the 'r' keyword to indicate regular
expressions\n instead of strings.\n\n\n** Metacharacters\n\n - $ ::\n -
^ :: inside a group, specifies complementation\n - \\ :: used to escape
from the default meaning to a new meaning. Eg, \\w, \\[, \\\\, etc.\n - .
::\n\n** Special symbols ::\n\n - \\d :: matches any decimal\n - \\s ::
any whitespace character [\\t\\n\\r\\f\\v]\n - \\w :: any alphanumeric
character\n - . :: matches any character except newline\n - more\n\n\n**
Compiling regexes\n\n - pat = re.compile(r\"ab*\") :: This \"compiles\" the
regular\n expression =ab*=. The result is a pattern object.\n\n**
Using regexes\n\n\n - re.match(r<pattern>, string) :: returns an object
that contains\n a match at the BEGINNING of the string, else None.\n\n
- re.search(r<pattern>, string) :: returns an object that contains a\n
match ANYWHERE in the string, else None\n\n - re.findall(r<pattern>,
string) :: returns a list that\n contains all the matches of the
pattern in the string.\n\n - re.finditer(r<pattern>, string) :: returns an
iterator that\n contains all the matches of the pattern in the
string.\n\n\n** Operations on the matched object\n\n - group() :: returns
the string matched\n - start() :: returns the start position of the
match\n - end() :: returns the end position of the match\n - span() ::
returns the group of starting and ending positions.\n\n* Examples\n\n We
cover some simple examples of regular expressions\n\n** Basic

There's a correction. On the first pass, no html file is generated. But I
feel it must have something to do with the Python shell buffers that get
created (and are left with the comint:run status) after each export.
