Not a bug in libxml2, but the embeded copy of zlib in your proprietary program is too low.

Status in “libxml2” package in Ubuntu: Invalid Bug description: After an upgrade to Ubuntu 12.10 (64 bit, from 12.04) I appear to have zlib1g:i386 version 1:1.2.7.dfsg-13 and libxml2:i386 version 2.8.0+dfsg1-5ubuntu2. These appear to be the newest versions in the repositories. Running a third party proprietary program (Guitar Pro) that relies on libxml2:i386, I get the following error: /opt/GuitarPro6/launcher.sh ./GuitarPro: /opt/GuitarPro6/./libz.so.1: version `ZLIB_1.2.3.3' not found (required by /usr/lib/i386-linux-gnu/libxml2.so.2) I've read elsewhere [1] that zlib > 1.2.5 breaks libxml2 < 2.7.6.dfsg-2, so I'm wondering whether perhaps zlib 1.2.7 might break libxml2 2.8 as well, but that this isn't reflected in the dependencies. Apologies if this is actually a bug with Guitar Pro. It's not even supported on Ubuntu > 10.04 32bit (grumble grumble), so I'm playing with fire anyhow trying to get it to work. But it was working before with zlib1g:i386 (1:1.2.3.4.dfsg-3ubuntu4) and libxml2:i386 (2.7.8.dfsg-5.1ubuntu4.1)! So I'd like to know if there's any suggestions as to what I can do about this, or if it's likely to be a bug.
