```
* The upload fixes the bug as
https://github.com/canonical/apport/pull/540 adds a fix to catch all
error cases as the function _read_maps reads /proc/pid/maps but will
return a string starting with Error: in case of an OSError.
[ Test Plan ]
* This crash can be reproduced by having apport try to process a
crash dump for a process that has already exited:
```
FAKE_PID_DIR=$(mktemp -d)
FAKE_PID=99999
mkdir -p "$FAKE_PID_DIR/fd"
mount --bind '$FAKE_PID_DIR' /proc/$FAKE_PID 2>/dev/null || true
apport -p $FAKE_PID 2>&1 || true
```
* https://github.com/canonical/apport/pull/540 also introduced a unit
test for this.
[ Where problems could occur ]
* We are adding an error case to the error handler so a syntax error
might lead to incorrect error message or failure to build.
* Since apport is primarily for crash reports, user experience is
unlikely to be affected much.
