According to the comments it seems to me that this bug is caused of the "single" update of the acroread package to version 9.1.0-*. Strong hint to that: Other packages of the acroread family are not available from the medibuntu repository at the moment (most likely because they are being updated). Be patient or try the workaround, as they work fine.
