What kinds of problems?  The wallpaper API is...  ummm...  simple: set a
wallpaper bitmap.  Home gets told the wallpaper changed.  It loads and
displays it.  The end.

Anyway, as of 2.0 home doesn't have any involvement with the wallpaper at
all.  It just uses Theme.Wallpaper for its activity, which has the system
put it on top of whatever the current wallpaper is.  This is true for both
the old and new launcher, and started with 2.0 in Droid so hasn't changed
with either 2.1 or Nexus.
