Title:
Apparmor prevents the crash reporter from working
Status in firefox package in Ubuntu:
Incomplete
Bug description:
Recently Firefox crashed on me twice. Looking at "about:crashes" showed
nothing but very old crash reports.
Looking at the audit.log I found that Apparmor is not allowing the crash
report to use ptrace:
type=AVC msg=audit(1400782417.435:3304): apparmor="DENIED" operation="ptrace"

Those messages are not in the usual format as I run auditd but the
actual content should be the same.
