[Benjamin Drung]

There are tousand of reports for noble plus ones for oracular and plucky
with that stack:

```
Traceback (most recent call last):
  File "/usr/share/apport/whoopsie-upload-all", line 246, in <module>
    main()
  File "/usr/share/apport/whoopsie-upload-all", line 228, in main
    stamps = collect_info()
             ^^^^^^^^^^^^^^
  File "/usr/share/apport/whoopsie-upload-all", line 162, in collect_info
    res = process_report(r)
          ^^^^^^^^^^^^^^^^^
  File "/usr/share/apport/whoopsie-upload-all", line 112, in process_report
    r.add_gdb_info()
  File "/usr/lib/python3/dist-packages/apport/report.py", line 1022, in add_gdb_info
    addr_signature = self.crash_signature_addresses()
                     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3/dist-packages/apport/report.py", line 1761, in crash_signature_addresses
    offset = self._address_to_offset(addr)
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3/dist-packages/apport/report.py", line 1969, in _address_to_offset
    self._build_proc_maps_cache()
  File "/usr/lib/python3/dist-packages/apport/report.py", line 2005, in _build_proc_maps_cache
    assert m, "cannot parse ProcMaps line: " + line
           ^
AssertionError: cannot parse ProcMaps line: Error: [Errno 3] No such process: 'maps'
```

So this workaround is not enough:

```
    def crash_signature_addresses(self) -> str | None:
        # [...]
        if "Errno 13" in self["ProcMaps"]:
            return None
```
