When using Psi as a pre-compiled package, Psi freezes during startup. This becomes evident through the appearance in the task-bar's nofication area: Instead of Psi's icon showing the online/offline status, another running application's icon is drawn there instead (I assume due to uninitialized graphics memory). No Psi window appears. Psi can be exited through pressing Ctrl+C if it was started on the command line.
On the command line, the following output appears:

# psi

When compiling Psi myself using makepkg, PKGBUILD etc from projects.archlinux.org and installing this package, the same behavior appears.
The problem does not happen if I compile Psi myself (no makepkg) following the same receipe as described in PKGBUILD, i.e. applying the patch, running ./configure and make.

I am using a Psi configuration in my home folder which I have inherited from an old machine (different Linux distribution, older Psi), but it is working with my self-compiled Psi.

I am using KDE 4.9.3-1 as the desktop environment and Qt 4.8.3-5.
