I think it comes from the '._something.pth' that Textmate created as a
temporary file when I edited a 'pth' file. The 'macromates' text in
their is from textmate. I'm not sure if it is Mac specific or Texmate
specific, but those temp files are really annoying.

Thanks.

It may be actually a Parallels issue - I've installed 2.5.1 on Vista (just  
once, on a real PC) and it worked fine. Anyway a better place for bug  
reports is bugs.python.org

Mmm, maybe you should check all your .pth files - looks like this strange  
path comes from one of them.

Buffer Overflow with Python 2.5 on Vista in import site

2008-03-29 Thread Fuzzyman 
A very odd error with Python 2.5 (both 2.5.1 and 2.5.2 from the
official msi installers and running on Vista under Parallels on the
Mac).

'import site' fails due to a string in sys.path that contains a huge
number of null bytes.

The error is actually in ntpath - I adjusted it to print the paths it
is working with and a string on encountering the bad path.

Because 'import site' is executed twice with the following code I
snipped the first dump and only print the one with the traceback:

C:\Users\Administrator>python -c "import site"

[snip]

'import site' failed; use -v for traceback
set(['c:\\python25\\lib\\plat-win', 'c:\\windows\\system32\
\python25.zip', 'c:\\
python25', 'c:\\python25\\lib\\lib-tk', 'c:\\users\\administrator', 'c:
\\python2
5\\dlls', 'c:\\python25\\lib', 'c:\\python25\\lib\\site-packages'])

Odd. Anyone got any clues?
