title: Source Tree crashes after installing
body: <p>I have created a repository in Bitbucket and wanted to clone it in Source Tree but then Source Tree crashed. I checked the log file in %AppData% and it states there that it is because of a OutOfMemory exception. 
  I reinstalled Source Tree but now, right after installation completes, Source Tree crashes with the same error code. 
  Does anyone have any idea how to solve this problem?</p>
  
  <p>Here is the .log file (at least the first part)</p>
