I den stabile distribution (lenny), er disse problemer rettet i version 1.3-release-7+lenny1.

I den gamle stabile distribution (etch), er disse problemer rettet i version 1.3-15etch3.

I distributionen testing (squeeze) og i den ustabile distribution (sid), er disse problemer rettet i version 1.3-release-8.
