Please unblock package lame
Dear release team,
the lame package in unstable contains some bug fixes that are
considered security-relevant. The package has already been updated in
stable as requested in #779083, but I somehow forgot to request its
transition to testing until now -- sorry.

+Subject: Fix decision if sample rate ratio is an integer value or not
+ If the sample rate of the input file is sufficiently close to an
+ integer multiple of the output sample rate, the value of the intratio
+ variable is calculated incorrectly. This leads to further values
+ being miscalculated up to the joff variable which is used as an index
+ to dereference the esv->blackfilt array. This leads top an overflow
+ and causes a segmentation fault.
