Although my models used to work fine.... after reinstalling player-gazebo in my work machine they fail to load with the following errors:

loading /usr/not-backed-up/PhDProgramming/Experiments_2_Launch_Files/worlds/./Table.so...
error   : error loading plugin: /usr/not-backed-up/PhDProgramming/Experiments_2_Launch_Files/worlds/./Table.so: undefined symbol: _ZN12ModelFactory13RegisterModelEPKcS1_PFP5ModelP5WorldE

error   : error loading plugin: /usr/not-backed-up/PSG//lib/gazebo/plugins/Table.so: undefined symbol: _ZN12ModelFactory13RegisterModelEPKcS1_PFP5ModelP5WorldE

Gazebo is: 0.5.1
Player is : 1.6.2

Any help?
