-- Information about the crash:
- What I was doing when the application crashed:
estava eu escrevando este texto e derrepente a barra inteira do lançador desapareceu, sendo que antes disso eu clique com o botão direito do mouse e selecionei o item para alterar para o lançador clássico e não mais quis voltar a versão oxigeny e a gora mais essa a barra sumiu de vez.
existe alguma solução?

The crash can be reproduced every time.
