[Bug 2081604] Re: pk-debconf-helper crashed with SIGSEGV in pk_client_helper_copy_stdout_cb()

[Sebastien Bacher]

@Alessandro,

Checking the error tracker, it seems we have an entry for the signature
https://errors.ubuntu.com/problem/96ef40e728f33ee0d271e4befe88e84706a65216

If we wanted to SRU the testcase could be 'check that there is no new
report against the fixed version'

That said the error metrics are rather low and we haven't got complains
about user visible consequences so it's probably a low priority for a
SRU at this point.

Could you share a reference to the upstream fix and in which version it
is (going to be) included?
