The QCA library (https://launchpad.net/ubuntu/+source/qca) is currently used by:

- psi
- mailody

The problem that will arise with the sync is: QCA1 is a Qt3 library used by Qt3 applications; QCA2 is a Qt4 library used by Qt4 applications. Both, however, are managed in Debian as the same source package (qca; http://packages.qa.debian.org/q/qca.html) and their binaries are conflicting (libqca.so). QCA1 programs cannot be easily ported to QCA2.

While the Debian source package for QCA2 is qca, the Ubuntu source package qca2 has spent quite some time in NEW. It should probably be nuked.

Psi version 0.11 RC2 uses Qt4 and requires QCA2 version 2.0.0 beta7 - the version currently in Debian experimental. So we can sync that and package Psi. (Bug #120315 is dedicated to packaging Psi 0.11).

Mailody is a more complicated case, there is no public Qt4/QCA2 release yet, although porting efforts are underway. I will inquire toma about their status.

For now, as a temporary solution until the Qt4 versions are accepted into Ubuntu, we can do the following:

1. Move source package qca to another name (changing the library name correspondingly).
2. Rebuild current versions of psi and mailody against the new package.
3. Sync qca_2.0.0~beta7 from Debian.
4. Upgrade psi from 0.10 to 0.11~rc2.

Debdiffs to follow.
