I get the same segfault when running moltengamepad immediately after installing. The change xordspar0 put in the PKGBUILD and the patch to the postinstall script don't fix it.

Subject: [PATCH] Correctly create the gamepad user

The post install script fails to create the gamepad user. This patch
fixes that.

When I run moltengamepad on the command line after installing this, I get a segfault right away. However, when I add options=(debug !strip) to the PKGBUILD, the segfault goes away.
