Fixing this (the permissions of the .crash file) in the apport code for
recoverable_problem is not possible given who recoverable_problem is
running as.

I tried having recoverable_problem use os.chown(report_path,
pidstat.st_uid, gid) and this ended up creating a crash in
recoverable_problem.

Traceback:
 Traceback (most recent call last):
   File "/usr/share/apport/recoverable_problem", line 85, in <module>
     main()
   File "/usr/share/apport/recoverable_problem", line 77, in main
     os.chown(report_path, pidstat.st_uid, gid)

Title:
  recoverable problem crash files created which whoopsie cannot read

Status in “apport” package in Ubuntu:
  New

Bug description:
  I've seen it happen that recoverable problems are created that
  whoopsie has no permission to read and subsequently cannot upload the
  crash file to the error tracker.
