Just compiled v0.8.2 from git. I'm running Crunchbang (http://crunchbanglinux.org/) which is basically just a minimal Debian Squeeze install with a bare Openbox.

Kdenlive launches, runs through the first few windows specifying default settings, etc. then crashes on kbuildsycoca4 because of an openbox.desktop file in /usr/share/applications with type "XSession" instead of "Application" or "Service".

Probably an easy fix. The openbox.desktop file:


[Desktop Entry]
Encoding=UTF-8
Name=Openbox
Comment=Log in using the Openbox window manager (without a session manager)
Comment[pt_BR]=Use esta sessãpara executar o Openbox como o seu ambiente de trabalho
Exec=/usr/bin/openbox-session
TryExec=/usr/bin/openbox-session
Icon=openbox.png
