Bug#862558: plasma-workspace: Freezes during login with fresh installed Stretch Japanese environment

[Hideki Yamane <henrich@debian.org>]

Source: plasma-workspace
Severity: grave
Justification: renders package unusable

Dear Maintainers,

 After installation of Strech on Japanese environment, ksplashqml stops during
 login. At that time, process was like below or just <defunct> status.

 1511 ?        Sl     0:22 ksplashqml Breeze --pid
 1526 ?        Sl     0:00  \_ /usr/lib/mozc/mozc_server
 1532 ?        Sl     0:00  \_ /usr/lib/x86_64-linux-gnu/uim/uim-candwin-qt5 -v

 Then kill mozc-server process, then I could see desktop.

 I'm not sure why ksplashqml need to talk to Input method server directly.


Step to reproduce)

 1. Install Stretch
 2. Select Japanese environment
 3. Select KDE for desktop and ssh-server
 4. After installation, just login (and freezes)
 5. Login from ssh client and kill mozc_server process
