Comment (by nix_nix):

 Of course, having asked for help, I figured it out. The fundamental
 problem with "remove" is that the currently selected theme is going away,
 so you have to select a new one. To correctly select a new theme, you do a
 purple_prefs_set_string(PIDGIN_PREFS_ROOT "/smileys/theme",
 new_theme->name) when you're about to delete current_smiley_theme from the
 smiley_themes GSList. You choose new_theme as follows:
   - The next theme in the smiley_themes GSList, if it's not NULL,
   - otherwise, the first theme, if current_smiley_theme is not the first
 theme,
   - otherwise NULL (We Should Never Get Here (TM) - especially since
 removing 'none' is explicitly checked for and disallowed removal in
 gtkprefs.c)
