Setting git PATH inside Options while debugging crashes Creator

Steps to reproduce:

• make sure git is not configured in PATH
• start Creator with clean settings
• create or open a Qt UI project
• use a kit that is configured to use a Qt inside a git repository
• start debugging by pushing step into
• step further into until you reach a Qt class inside the repository (a warning should pop up of having a unsupported git version)
• go to Tools -> Options -> Version Control -> git and configure the git path
• hit OK

Current result:

• Creator crashes

Note: if you had the path set once - this is no more reproducable.

Backtrace is pretty short for the main thread:
