LibreOffice 4.3.0 hasn’t been officially released. The version you are using is Release Candidate 3 or 4.3.0.3. That malfunction was detected and fixed. There will be a 4.3.0.4 release (i.e. Candidate 4) soon (which hopefully will be the last and the same as the official 4.3.0)
In any case the first few versions of each branch i.e. any version ending with 0, 1, 2 sometimes 3) are not recommended for production (therefore named Fresh releases).
Each new branch has new features but also regressions which might cause problems.
Unless there is some new feature that you badly need in 4.3.0 you are best served with the 4.2 branch (build 4.2.6 should be out in a few days)
