Hi all, First of all, sorry if this isn't the list where I have to post this. And sorry for my english.

As the subject says, I'm having problems with the attached email, when I try to get a email object reading the attached file, the python process gets hang and gets all cpu. I have debuged my code to find where it happens, and I found that is parsegen method of the FeedParser class. I know that the email format is wrong but I don't know why python hangs. following paste the code showing where hangs. [snip] bash-3.00$ python Python 2.5.1 (r251:54863, Feb 28 2008, 07:48:25) [GCC 3.4.6] on sunos5 Type "help", "copyright", "credits" or "license" for more information. >>> import email >>> fp = open('raro.txt') >>> mail = email.messagefromfile(fp) never return............

When you think you found a problem with python, please submit an issue in the python issue tracker: http://bugs.python.org/

In your case, I suspect some regular expression trying to match all the empty lines of the message, one character at a time.
