After updating my system i'm having troubles opening cmake based projects in Qt Creator.
When opening a CMakeLists.txt file the source files are not shown in the Edit view of creator.
The Projects view contains the correct settings however, and building the project also does work.
I'm just not able to view the project tree...
The same project loaded fine in the previous version of creator.
I verified that the CMakeProjectManager plugin is loaded.

unfortunately i cannot share the source of this project, however it seems to happen with all projects i've tried.
For example i found this (unrelated) project on github which reproduces the problem: https://github.com/marcbowes/mxitc
