+git-annex version: 4.20130323

+Running the webapp with SELinux enabled:

+    /home/zerodogg/bin/git-annex: line 25:  5801 Segmentation fault      (core dumped) "$base/runshell" git-annex "$@"
+
+After disabling SELinux it works just fine. This is on a freshly installed (default settings) Fedora 18 on x86-64.
+
+Running the assistant also works, but segfaults when attempting to open the webapp:
