#365 0.9.7 Qt error in constraintsdialog.cpp
Perhaps the Qt requirement got bumped again for 0.9.7, I get this with Qt-4.4.3:

You are correct, the Qt dependency for Avogadro was bumped to 0.9.7. This was in the docs, but it was not in the CMakeLists.txt for this release. I have committed this in head, which has not compiled without Qt 4.5 since mid-June.
This isn't a bug, so I'm closing the tracker item.
