During further investigation, i found that apps subjected to this bug, starts to work when i downgrade cairo library to one from Ubuntu 12.04 LTS, which version is known to be free from this bug. This is cairo 1.10, libcairo2_1.10.2-6.1ubuntu2_i386.deb. Using it with 'dpkg -i' solves these problems. But adds many other problems: nautilus, synaptic, gedit, and even mc, refuses to work anymore.
So i try to have both libs, and feed only apps subjected to cairo bug, with old library (i extract .deb package as archived file to get old library binary 'libcairo.so.2').
To obtain this, i try LD_PRELOAD.
For gimp and eclipse, i use simple method that works from command line only:

[code]
echo "alias gimp=LD_PRELOAD=/home/test/Downloads/libcairo2_1.10.2-6.1ubuntu2_i386/usr/lib/i386-linux-gnu/libcairo.so.2 gimp" >> ~/.bash_aliases
echo "alias eclipse=LD_PRELOAD=/home/test/Downloads/libcairo2_1.10.2-6.1ubuntu2_i386/usr/lib/i386-linux-gnu/libcairo.so.2 /opt/eclipse/eclipse" >> ~/.bash_aliases
[/code]

For LO, i try to make fully transparent setup which will work also from GUI, Ubuntu Main Menu, etc. NOTE: Using this way, it is NOT possible to open documents with spaces in file name. It is don't care for me; i can't find any possibility to replace '$@' to something supporting spaces.

[code]
sudo rm /usr/bin/soffice # this is just a link
sudo rm /usr/bin/libreoffice # this is just a link
sudo touch /usr/bin/soffice
sudo chmod a+rwx /usr/bin/soffice
sudo echo "LD_PRELOAD=/home/test/Downloads/libcairo2_1.10.2-6.1ubuntu2_i386/usr/lib/i386-linux-gnu/libcairo.so.2 /usr/lib/libreoffice/program/soffice \$@" > /usr/bin/soffice
sudo cp /usr/bin/soffice /usr/bin/libreoffice
[/code]

This all is probably ugly and dirty, but finally let me really switch to Ubuntu 14.04.3 LTS from 12.04 LTS for everyday production use. Thanks.
