We can also see that crash reporting works with /proc/sys/fs/protected_regular set to 1.

Subsequently, the crash reports are incomplete and not getting uploaded to the Error Tracker therefore Ubuntu developers may be missing out on important crash reports. [Test Case] 1) Confirm /proc/sys/fs/protected_regular is set to 1. 2) Run an application as your user and cause it to crash. (kill -11 $APP) 3) Confirm there is a crash report in /var/crash 4) Run 'sudo /usr/share/apport/whoopsie-upload-all' 5) Observe the Traceback in this bug report is produced by whoopsie-upload-all. With the version of apport from -proposed the Traceback will not occur and a .uploaded file will be created for the corresponding .crash file. [Regression Potential] Not all systems may have /proc/sys/fs/protected_regular set to 1, so we should also test the case where /proc/sys/fs/protected_regular is set to 0. This can be done by manually changing the value and running through the test case above and confirming that a .uploaded file is created for the .crash file. Original Description -------------------- The Ubuntu Error Tracker has been receiving reports about a problem regarding apport.
