CMake project with many targets causes crash when selecting target at end of the list in build steps

We have a CMake project with many targets. When selecting a target towards the end of the list in the make build step QtCreator dumps core. It seems to vary how close to the end of the list I can go before it crashes.

I have attached a minimal example that reproduces the problem.
Open it in QtCreator and select the last target in the list in the build settings.
