[Bug 1353171] Re: Misparses dpkg status line, fails to write apport reports

[Brian Murray]

** Description changed:

+ Test Case
+ ---------
+ 1) sudo apt-add-repository ppa:daisy-pluckers/daisy-seeds
+ 2) sudo apt-get update
+ 3) sudo apt-get install crash-in-postinst
+ 4) observe a package installation failure dialog
+ 
+ With the version of apt in the archive you will *not* receive a crash
+ file in /var/crash. If you install the version of apt from -proposed you
+ should receive a crash file in /var/crash and an apport dialog should
+ appear.
+ 
  For a while apt has not been writing apport reports for dpkg maintainer
  script errors. Here’s why:
  
  • pkgDPkgPM::ProcessDpkgStatusLine sees a line like
  "status: cyrus-clients : error : subprocess installed post-installation script returned error exit status 1".
  • StringSplit splits it into
  list == {"status", "cyrus-clients ", "error ", "subprocess installed post-installation script returned error exit status 1"}.
  • pkgname is set to Strip(list[1]) == "cyrus-clients".
  • However, the original list[1] == "cyrus-clients " (with a trailing space) is passed to WriteApportReport.
  • WriteApport fails to find "cyrus-clients " in the cache, and bails out.
  
  Patch attached.
