[Bug-AUCTeX] TeX-next-error puts me in

[giacomo]

i'm using a debian sid system, the Emacs and auctex versions are

"GNU Emacs 23.4.1 (i486-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2012-04-07 on biber, modified by Debian"

auctex 11.86-10  integrated document editing environment for TeX

when i compile an erroneous latex source i'm prompted to go to the error
position, but when i press "C-c `" in the latex buffer a new buffer is created, 
named "Tex Live 2011" and auctex make it the current buffer

"Tex Live 2011" is void, if i kill it or i switch buffer to get back to
the latex buffer the cursor in the latex buffer is not moved to the error
position

don't know if this is relevant, but i have both a tlmgr managed texlive in
/usr/local and Debian's texlive under /usr

for what is worth, this "Tex Live 2011" buffer thing happens also when i use
XEmacs
