I think I solved the problem. When closing the flatpak-install, terminal said something about a corrupt JPG. So I went in the flatpak-TB through many of my e-mails and erased a lot of mails with jpg-attachments. Then I copied the flatpak-mail-folder to the snap-mail-location, and now the snap-TB opens everything as expected. So it must have been a corrupt attachment - or I really have a disc-problem. I can check that later, but I think now that there is no software bug...
