Bug description:
The changes made in the following commit, which backported a number of
changes to the procps package in precise, result in various procps
utilities crashing with a SIGSEGV if the file2str function in
proc/readproc.c reads zero bytes.

/precise-updates/revision/61
This corresponds to the following procps package version:
1:3.2.8-11ubuntu6.1
Prior to this changeset, file2str would return -1 if the read failed;
now it does not, which is not expected by other parts of the procps
codebase, hence the crash.
Upstream have fixed this issue in the following commit:
https://www.gitorious.org/procps/procps/commit/526bc5dfa924177e68be0123bd67e3370955f924
