    Description

      The QtCreator version bundled with the latest Qt5.2.0 rc1-snapshot for 32bit Linux

      qt-linux-opensource-5.2.0-rc1-x86-offline_2013-11-27_11-26-05-177.run

      freezes on startup. It shows the menubar, and the toolbars on the left and bottom. The main screen part is not filled with anything yet when it hangs (appears "transparent"). I think it was about to show the "welcome" screen.

      Full backtrace from gdb:
