If I kill gnome-shell the crash file is written correctly:
```
$ killall -11 gnome-shell
$ apport-retrace -g /var/crash/_usr_bin_gnome-shell.1000.crash

Title:
Repeatedly unusable truncated crash files
Status in apport package in Ubuntu:
Triaged
Bug description:
Repeatedly unusable truncated crash files:
Bug 2012974, bug 2015842, bug 2015140, bug 2012075
Based on my own testing, the problems seems to happen if multiple
binaries crash simultaneously (like at logout). One crash file gets
fully written and the other is incomplete.
If I remove apport from the equation and just get the kernel to dump
core files then the core files are always written reliably (should be
several hundred MB in the case of gnome-shell).
Running `apport-retrace -g $crash` on the .crash files will fail with
"/tmp/apport_core_[...] is not a core dump: file format not
recognized"
