Ok, so the missing export of $DISPLAY appears to be the problem (amarok requires this, too).

Here's a quote from at.c however:
    /* Write out the environment. Anything that may look like a
     * special character to the shell is quoted, except for \n, which is
     * done with a pair of ""'s. Dont't export the no_export list (such
     * as TERM or DISPLAY) because we don't want these.
     */
where no_export is:
    "TERM", "DISPLAY", "_", "SHELLOPTS", "BASH_VERSINFO", "EUID", "GROUPS", "PPID", "UID"
