Comment 5 for bug 719764

ibidem, this issue is unreproducible in LibreOffice Writer via the Terminal:

cd ~/Desktop && wget https://bugs.launchpad.net/ubuntu/+source/abiword/+bug/719764/+attachment/2133267/+files/lab4.tar.bz2 && file-roller -h lab4.tar.bz2 && cd lab4 && lowriter -nologo lab4.rtf

typed a few characters, saved the file, closed it, reopened:

lowriter -nologo lab4.rtf

the rows remained gray. Does this work for you?
