-Hmm, so runshell has some things like
-
-	for lib in $(cat "$base/libdirs"); do
-		GIT_ANNEX_LD_LIBRARY_PATH=...
-
-Which, with an unusual IFS, probably set the environment variable to
-something bogus. Which seems the kind of thing that could break things
-badly enough to segfault.
-
-I have so far not been able to reproduce it, I tried:
-
-	tar zxvf ~/src/git-annex/tmp/git-annex-standalone-amd64.tar.gz
-	cd git-annex.linux/
-	IFS=$'\013' ./git-annex version
-
-But this may involve the system the standalone build is used in, if the
-problem is this is breaking its isolation from that system. So might need a
-particular version skew between the two.
-
-I've applied the obvious changes, so please verify the fix.
