--- Comment #2 from Alex <alex...@gmail.com> --- The crash was apparently caused by some missing packages. After installing an alternate desktop environment, switching back to Plasma somehow triggered the detection of the missing packages and I was prompted to install them. After that installation, I was able to add Japanese language with no crashes. -- You are receiving this mail because: You are watching all bug changes.
