Bug#879698: slashtime: will not start with Wayland

[Markus Koschany]

Package: slashtime
Version: 0.5.13-1
Severity: normal

Slashtime won't start and throws an exception with Wayland. This is
probably a bug in libjava-gnome-java but maybe some adjustments in
slashtime are required as well.

Warning: ~/.tzlist not found. Using fallback Place list instead.
Exception in thread "main" org.gnome.glib.FatalError:
No mapping for GdkWaylandScreen (yet!)
