Re[1]: speedbar refresh hangs emacs when visited directory is deleted

[Eric M. Ludlam]

Hi,

  This patch should fix it.  The patch is against my working version
of speedbar, but the function it patches has not changed.

        speedbar.el (speedbar-default-directory-list): Made robust against
        deleted directories.

Enjoy
Eric
