I am observing the same bizarre issue on ArchLinux.

Good question. Here's what I've found so far:
    - The path with the framework component is used if and only if
      QtEnvironment::frameworkBuild is true.
    - Qt Creator sets this flag to the value of 
BaseQtVersion::isFrameworkBuild().
    - This flags can only be true if the CONFIG value of the respective Qt 
version
      contains "qt_framework".
    - All code along this path looks fine at first glance.
    - Trying to reproduce the problem by building Qt Creator myself on the very
      same ArchLinux installation failed: Everything worked fine with this one.

In conclusion, I see two possible reasons for the problem:
    - We have a subtle case of undefined or at least non-deterministic behavior
      in the relevant code path. I don't see it, though.
    - Something went wrong when building the distribution package (buggy 
compiler?).
      Seems like a long shot, but stranger things have happened. 

Now that I think of it, I notice I used clang in my aforementioned attempt to 
reproduce the problem. I'll try again with gcc 7.
