Hey guys. I'm runing sqlmap for the first time in a clean Archlinux installation, and i'm getting exceptions related to Magic files not loeaded.

This is the error itself:

[12:56:00] [CRITICAL] unhandled exception in sqlmap/1.0-dev-1f2e5a9, retry your run with the latest development version from the GitHub repository. If the exception persists, please send by e-mail to 'sqlmap-users@lists.sourceforge.net' or open a new issue at 'https://github.com/sqlmapproject/sqlmap/issues/new' with the following text and any information required to reproduce the bug. The developers will try to reproduce the bug, fix it accordingly and get back to you.

Any hints on how to get this fixed?
Thanks!
