Hello Sidnei, 

What happened to the uploads on cheeseshop. I can only find the windows eggs 
for 1.2.1 the ones for 1.3 are missing. Have they been removed or is there a 
problem with cheeseshop? 

Kind regards,
Michael

Yey, the beta works great here.

Thanks.

To answer my own E-mail. A search on cheeseshop did not find the 1.3beta 
release. I found it under 

http://cheeseshop.python.org/pypi/lxml/1.3beta 

The obvious location of course. I do not know why the search did not return 
it, since I found it yesterday.
Nevertheless, thank you once again for providing pre-compiled binary builds 
for windows. 

Kind regards,
Michael

*** glibc detected *** free(): invalid pointer: 0x086449e7 ***

Hi,

I'm getting this error at times using lxml:

*** glibc detected *** free(): invalid pointer: 0x086449e7 ***

Unfortunately the smallest test fixture I have that does this involves 
running all of TurboGears - when I do this without TurboGears I don't 
get the error.  However, I've got a backtrace from gdb that points it's 
finger at libxml2.  I'm trying here first in case this is really an lxml 
problem.

I thought I'd tried this before (I've been hunting this bug a while), 
and I had, but now this is narrowed down a bit it's more interesting. 
1.3beta still abends:

*** glibc detected *** free(): invalid pointer: 0x085a8a8d ***

But the backtrace is different:

I shall try that now.

Yep, I thought that might be the case.  To join things up, here's the bug:
