Comment 3 for bug 1697705

Quoting https://serverfault.com/a/883115:

> NUL bytes in the syslog are a common effect of a crash that prevented the system from cleanly syncing and unmounting the filesystem. They don't give an indication of what actually triggered the crash.

Usually complete system crashes are caused by some fault in drivers, the kernel, hardware, etc. It is very unlikely that Variety, a desktop program working with high level desktop components is the direct cause of issues like this.

Without any further leads, I'm marking this issue as invalid.
