This bug was fixed in the package apport - 2.20.2-0ubuntu1
---------------
apport (2.20.2-0ubuntu1) yakkety; urgency=medium
[ Brian Murray ]
* data/general-hooks/ubuntu.py: tag bug reports 'apport-hook-error' if they
have an attachment from an apport hook which crashed.
[ Martin Pitt ]
* New upstream release. Changes since our previous snapshot:
- Don't ignore OSError in Report.add_gdb_info(), as we do want to fail with
an
useful error message if gdb cannot be called in apport-retrace. Move the
catching to the UI as not having gdb installed is still fine for reporting
clients. (LP: #1579949)
- Show gdb error messages in Report.add_gdb_info() OSError exception when
gdb
fails. (LP: #1579897)
- hookutils, attach_root_command_outputs(): Return str again, like before
2.15.2. (LP: #1370259)
- Stop issuing "set architecture" gdb commands on ARM and Power; these only
applied to 32 bit platforms and are apparently not needed any more with
recent gdb versions. (LP: #1585702)
- Disable report.test_add_gdb_info_abort_libnih test case for now, as libnih
is broken under current Ubuntu (LP: #1580601)

Status in Apport:
Fix Released
Status in apport package in Ubuntu:

Bug description:
Apparently, the following gdb command fails but the error output is
not in subprocess's err output but in stdout.

Because stdout is not included in the raised error message it ended up
being hard to find out what the error really was.
111 raise OSError('Error: command %s failed with exit code %i:
%s' % (
112 str(command), sp.returncode, err))
