Crash on creating files or reloading the list of files in generic project manager

Ever since upgrading to 4.3.0 QtCreator easily crashes when creating new files or when updating the list of files in the <project>.files files via a simple 'git ls-files >project.files'.

The crash does not happen all the time, but often enough now to be annoying. I'm attaching the Crash reports from OSX for three different cases. The newest one was from changing the project.files file, the other two from creating new files in the project via the new file wizard inside qtcreator.
