xdvik version 22.84.10 (Xaw toolkit)
Libraries: kpathsea version 3.5.5, T1lib version 5.0.1
since the latest tetex upgrade, in a gentoo machine.
With this new version I'm experiencing a slow xdvi start-up, which does not affect the working speed - after loading, it works like it was working before.
After some experiences, I reported this in gentoo forums (http://forums.gentoo.org/viewtopic-t-319519.html) and got an workaround: running "LC_ALL=C xdvi" instead of "xdvi" /solves/ this issue.
