    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      libgssglue1                     0.3-4ubuntu0.1
    
    Ubuntu 11.10:
      libgssglue1                     0.3-1ubuntu1.1
    
    Ubuntu 11.04:
      libgssglue1                     0.1-4ubuntu1.1
    
    Ubuntu 10.04 LTS:
      libgssglue1                     0.1-4ubuntu0.1
