pmap: wrong output in extended format (-x option)

Binary package hint: procps

As of version 3.2.8-10ubuntu1 pmap -x always prints zero in Kbytes column and does not count summaries for RSS and dirty columns. For example:

$ pmap -x 2868
2868: /bin/bash
Address Kbytes RSS Dirty Mode Mapping
08048000 0 608 0 r-x-- bash
08107000 0 4 0 r---- bash
08108000 0 16 16 rw--- bash
0810d000 0 20 20 rw--- [ anon ]
09405000 0 2464 2044 rw--- [ anon ]
...
b7855000 0 4 4 rw--- ld-2.12.1.so
bfb1f000 0 24 24 rw--- [ stack ]
-------- ------- ------- ------- -------
total kB 9984 - - -

I think it should print something like:

$ ./pmap -x 2868
2868: /bin/bash
Address Kbytes RSS Dirty Mode Mapping
08048000 764 608 0 r-x-- bash
