The python3 bindings create unicode objects from application strings on the guest (i.e. installed rpm, deb packages). It is documented that rpm package fields such as description should be utf8 encoded - however in some cases they are not a valid unicode string, on SLES11 SP4 the following packages fail to be converted to unicode using guestfs_int_py_fromstring() (which invokes PyUnicode_FromString()): PackageKit aaa_base coreutils dejavu desktop-data-SLED gnome-utils hunspell hunspell-32bit hunspell-tools libblocxx6 libexif libgphoto2 libgtksourceview-2_0-0 libmpfr1 libopensc2 libopensc2-32bit liborc-0_4-0 libpackagekit-glib10 libpixman-1-0 libpixman-1-0-32bit libpoppler-glib4 libpoppler5 libsensors3 libtelepathy-glib0 m4 opensc opensc-32bit permissions pinentry poppler-tools python-gtksourceview splashy syslog-ng tar tightvnc xorg-x11 xorg-x11-xauth yast2-mouse This is a surgical fix for inspect_list_applications2()'s description field.
