Ligature problem demonstration
1.) Install Linux Libertine G font.
2.) Open the attached .odp and place the cursor at the end of the word "mellet".
3.) type another "t".
A third "t" appears. When you remove the third "t" character, only one remains.
Repro with document.
This does not happen with v. 3.6.
