1. In Writer, invoke File -> Find and Replace.
2. A dialog appears.

Expected:
3. There are four buttons on the right hand side, i.e. "Find", "Find All",
"Replace", "Replace All".

Actual:
3. There are SIX buttons on the right hand side, i.e. "Find", "Find All",
"Replace", "Replace All" and two dummy buttons (no description, no action if
clicked) below.

Seems to be Linux specific.

Regression wrt OOo 2.0.1 and to m153.
