However, in comparison to version in testing (2.7.3~rc2-2.1), 
libpython2.7 not only removed two symbols (init_hashlib, init_ssl) but 
also added one (init_heapq). This new symbol doesn't have correct 
dependency declared in the symbols file. As a consequence, if you 
rebuild vim in unstable, and then run it against libpython2.7 from 
testing, you get this:

$ LD_BIND_NOW=1 vim
vim: symbol lookup error: vim: undefined symbol: init_heapq

>I'll check if other source packages are affected later.

I checked all i386 binaries depending on libpython2.7:

- There are no other users of init_hashlib.

- ntop uses init_ssl. However, the intention was to use this one:

$ readelf -s /usr/lib/ntop/libntopreport.so | grep -w init_ssl
    446: 00046480  1804 FUNC    GLOBAL DEFAULT   12 init_ssl

So if libpython2.7 dropping init_ssl makes any difference for ntop, then 
it should rather fix things than break them.
