Respondendo minha pergunta sozinho.
Acho que no começo minha pergunta foi pouco enganosa.
O sistema me informou que a falha poderia acontecer por causa da biblioteca de terceiros usada pelo Gimp (/usr/local/lib/libz.so.1.2.7).
Eu removi o link simbólico /usr/local/lib/libz.so.1 para /usr/local/lib/libz.so.1.2.7 e tracei com strace que a biblioteca padrão é usada

Isso não resolveu o problema.
Mas após algumas pesquisas adicionais, eu acho que descobri relatório de erros relacionado .
