Install TexStudio 2.7.0 for Ubuntu 13.10 (amd64) today, and on first start (or after deleting ~/.config/texstudio), TexStudio performs some kind of self-test.
Many tests fail, simply because the expected values are paths from some typical miktex windows install.
Furthermore, the self-test is a total surprise and seems more like a malfunction of some sort for the first few seconds. In fact, I quit texstudio 3 times before I let the tests run through and finally realized what it actually was.
This does not seem appropriate for a release build.
