Hi Andrew: Qt version might well be the issue, but there is another alternative explanation as well which is easy to check. Qt installations actually consist of two sets of libraries, those with a debug attribute and those without that attribute. All CMake versions for Windows were confusing which was which for builds without a specified type (the normal case) as discussed on a thread entitled "CMAKE_BUILD_TYPE not set on MinGW" on the CMake development list in June this year. The result of this CMake/Qt issue on Windows is bad Qt results which might be similar to what you are encountering on Debian and certainly similar to what I encountered some time ago for PLplot/qt on wine. Clint Stimpson said in the thread he thought the problem would not affect Linux, but my own feeling is you never really know for sure whether such assertions are correct until you test them. So just to see would you try this simple patch to Modules/UseQt4.cmake (http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=5a2b20;hp=672b6ca5e431f511f2638511b0128b6956f3e3ad) to see whether it solves your issue? In any case, that patch is going into CMake-2.8.6 (once that gets released) to fix the Qt on Windows issue with CMake, and it would be most interesting if that simple 3-line change made a difference to the symptoms you are seeing on Debian.
