first of all thanks for developing this nice tool!
It seems there is an Bug somewhere (?) - a litte strange one..
i can reproduce that after each second access to viewgits main page all is fine. the other 2 accesses will fail with exit code 128 @ file /inc/functions.php @ function run_git @ command "exec($cmd, $output, $ret);"
Im using viewgit-0.0.5.tar.gz (59.9 kB)
on RaspberryPi @ debian wheezy
with git version 188.8.131.52
and PHP Version 5.4.4-7
