Hello Marenz,

I have just tried to reproduce segfault with the provided archive:

[del@del-debian bugtest1 (master)]$ git diff
diff --git a/submodules/bugtest2 b/submodules/bugtest2
--- a/submodules/bugtest2
+++ b/submodules/bugtest2
@@ -1 +1 @@
-Subproject commit cd0b9ee2946d2df3626943347332a4d86f93b126
+Subproject commit cd0b9ee2946d2df3626943347332a4d86f93b126-dirty

No segfault occured. I am using

git version 2.6.2.308.g3b8f10c

Could you please specify which version of git you are using and also try 
to reproduce it with latest 2.6.2?
