Description of problem:

There are several failures in LSB test suite that were not present in Fedora 18
and are related to text_iter_* functions, for example:

---------------------------------------

Actually this is a regression between pango-1.34.0-1 and pango-1.34.1-1.

standalone reproducer for gtk_text_iter_starts_word() function

as an example I am adding a standalone reproducer for the
gtk_text_iter_starts_word() function.

# ./a.out | grep FAIL
FAIL: gtk_text_starts_word () returned not 1 incorrectly, line = 'word1word2
word3', pos = 4
FAIL: gtk_text_starts_word () returned not 1 incorrectly, line = 'word1word2
word3', pos = 5
FAIL: gtk_text_starts_word () returned not 1 incorrectly, line = 'word1_word2

--- Comment #2 from Akira TAGOH  ---
This behavior was introduced by this change:
https://git.gnome.org/browse/pango/commit/?id=1aeb5c840e25a7d8538f701659d77d...

According to the commit log, this change was needed to meet Unicode 6.2 specs
and the previous behavior was wrong. so this is not a bug. please fix the test
case instead.
