Solution found in this post

1. open “acroread” script ,maybe in /usr/bin/,or any other path you put it;

2. find this row (in line 418): Code:

echo $mfile| sed ‘s/libgtk-x11-\([0-9]*\).0.so.0.\([0-9]\)00.\([0-9]*\)\|\(.*\)/\1\2\3/g’

3. replace with: Code:

echo $mfile| sed ‘s/libgtk-x11-\([0-9]*\).0.so.0.\([0-9]*\)00.\([0-9]*\)\|\(.*\)/\1\2\3/g’
