Guia do colaborador

Direção de pesquisa
Investigue por que o registro do tipo GLib falha quando uma segunda sessão SSH é criada. Concentre se na inicialização de PangoFontMap e PangoCairoFontMap, possivelmente devido à dupla inicialização ou uso inadequado de cgo. Verifique o código de inicialização do occamy lib e a sequência de chamadas que levam aos avisos do GLib.
