Emacs-24.3 crash when browse-url

[Thierry Volpiatto]

Hi,
emacs crash when using M-x browse-url
I think the function that crash is `browse-url-xdg-open'
or its predicate `browse-url-can-use-xdg-open'.
There is no crash when using something else than
`browse-url-default-browser' for `browse-url-browser-function'
e.g:
(setq browse-url-browser-function 'browse-url-firefox)

This happen with this revision from trunk:
