Does it still work after you have saved some files from within Gedit
(which will then be listed as recently opened files)?

AFAIU it is a problem affecting many applications [1][2], mostly on
non-Gnome desktops like KDE and MacPorts (using Oxygen or no explicit -
i.e. stock/hicolor - icon theme), triggered by a change in GTK+ 2.22.x
for stock and fallback icons [3].

A known workaround e.g. for Inkscape 0.48.0 [4] and MyPaint is to
actually use the Gnome or Tango icon theme (via ~/.gtkrc-2.0) as main or
fallback icon theme. Just having the icon theme installed is not
sufficient to prevent the crash in the GtkRecentManager object. Try
adding this line to ~/.gtkrc-2.0 to prevent the crash:

gtk-fallback-icon-theme="gnome"

or, alternatively (if you prefer Tango icons):

gtk-fallback-icon-theme="tango"
