problems installing libgtk2.0-common (2.2.2-2)

[Gerard Sanromà Güell <gusage terra es>]

  Hello group,
  i cannot install libgtk2.0-common due to an undefined symbol g_printf.
  It's been probably caused due to an apt-get dist-upgrade to the debian 
unstable.

  Anyone knows how can i solve this problem or what is the cause of this 
problem ??

  Thanks.

  The output of an apt-get install -f which tries to install the packages that 
failed.

gusage:/etc# apt-get install -f
