Bug description:
  Minetest package is buggy in Ubuntu Trusty and Saucy (crashes when selecting Client->"Public Serverlist" and doesn't work Mods->"Online mod repository") and outdated - new minetest 0.4.9 was released few days ago.
  0.4.9 release contains some improvements and bugfixes.
  It would be nice if new Minetest 0.4.9 packages wouldn't crash when selecting Client->"Public Serverlist" and show no error when pressing Mods->"Online mod repository" in startup screen.

  0.4.8 → 0.4.9 New Features
  Logistic changes

      Add configurable font shadow (xyz)
      Directional fog + horizon colors (Taoki) 
  Other things

  Bug Fixes
   Fix line_of_sight() (sapier)
   Fix modstore/favourites hang by adding asynchronous Lua (sapier)
   Fix LevelDB maps (sfan5)
   Fix Lua mapgen override param handling (kwolekr)
   Fix leak and possible segfault in minetest.set_mapgen_params (kwolekr)
   Fix segfault in indev cave generation due to uninitialized variable (kwolekr)
   Check if width, height or start index of a list[] is negative (PilzAdam)
   Fix single character formspec field labels (BlockMen)
   Handle Lua errors in on_generate callbacks instead of throwing SIGABRT (kwolekr)
   Update mapgen params in ServerMap after Mapgen init (kwolekr) 

  Modding-related Changes
   Add area parameters back to calc_lighting() and set_lighting() (kwolekr)
   Add get_light_data() and set_light_data() to LuaVoxelManip (kwolekr)
   Add minetest.swap_node (Novatux)
   Assume a selection box for fences (0gb.us)
   Decoration: Add schematic Y-slice probability support (kwolekr)
   Add sneak and sneak_glitch in set_physics_override() (PilzAdam)
   Use a table in set_physics_override() (PilzAdam)
   Add 'on_prejoinplayer' callback (kaeza)

  Also I'm pasting terminal output after 0.4.8+repack2-3 crash when selecting Client->"Public Serverlist":
