Do you experience problems during downloading?
Check your connection in Status and Interface settings window.
Use Test Server in Config > Servers.
We will probably ask you to do a test using only basic settings.
Do you experience problems during repair or unpacking?
Enable +Debug logging in the Status and Interface settings window and share the relevant parts of the log here using [ code ] sections.
The warning must go and the 7zip option will be grayed-out when not available.
Whether or not 7zip is seen as a requirement is for the package builders to decide.

When the time comes to release a 0.8.x on the ppa, that will be added as a (recommended or suggested) dependency like the other archiving utils (unzip, unrar|rar). As will libavahi-compat-libdnssd1 and python-gtk2, needed for zeroconf and the tray icon.
