Git crash on different versions, including current

Hi everybody,

today I ran into a git issue on Windows 7/64. My directory structure looks like this, and I wondered why the content of a dir wouldn't get added.

C:\Users\chris\git\GoogleTestExtension -- .git -- ConsoleApplication1 (new) ----- gtest-1.7.0 dir (does not get added) ----- stuff that has been successfully added -- more stuff that's already under git control

So here's about what I did:
- Looked at it with Git Gui, noticed that gtest-1.7.0 is a submodule
- Deleted gtest-1.7.0/.git
- performed git add --all . within the gtest-1.7.0 dir => crash, output
below
- installed git 2.5.0
- uninstalled git 1.9.1
- deleted lock file
- performed git add --all . within the gtest-1.7.0 dir => crash, output
below

I could provide the according dir for reproducing the issue (I will now zip it for reference) - if anybody is interested, drop me an email.

All the best Christian
