O Plasmashell inicia, mas depois trava com um segfault no libQt5Quick.so.5.9.5

Question

Eu tenho um Kubuntu 18.04 instalado completamente novo, ou seja, não atualizado de versões mais antigas. É claro que apliquei todos os apt upgrade patches.

Enquanto o plasma funcionava bem antes por dois dias, ele agora estava quebrado (presumivelmente no decorrer da instalação de aplicativos). Não consigo reproduzir o que o fez quebrar, já que muita coisa foi instalada desde então.

Etapas para reproduzir:

faça login como usuário principal kayd (eu)

• carrega o plasmashell, exibe a barra de ferramentas, mas a barra de ferramentas parece ter uma entrada irregular no lado direito porque outras entradas parecem deslocadas para a esquerda.
• (ao mesmo tempo) a sessão é restaurada e por exemplo A janela do shell é aberta a partir da sessão salva anteriormente.
• (depois de segundos) a barra de ferramentas está desaparecendo, a imagem de segundo plano está desaparecendo

• exibe dmesg

No shell, digite "plasmashell"

Aqui está a saída do shell:

O que está quebrado / não está quebrado

• ainda posso iniciar aplicativos a partir do shell.
• Ao iniciar mais aplicativos, eu posso usar Alt-Tab para fazer o ciclo.
• Mover o mouse no canto superior esquerdo e superior direito faz organizar os aplicativos.
• Eu configurei outro usuário que tem sem problemas , alternar entre usuários funciona bem.
• Ao iniciar uma nova sessão para meu usuário, infelizmente o plasmashell também falha nesta segunda sessão.
• Eu removi completamente o diretório ~/.cache , como sugerido em outras postagens, e reiniciei, mas isso não resolveu meu problema.

Atualização:

As falhas não acontecem sempre, mas apenas a maior parte do tempo. Depois de uma reinicialização, ele conseguiu se recuperar após uma falha anterior, e essa mensagem pôde ser extraída:
