gst-plugin-scanner crashed with signal 7 in memset()

Xfce Panel Switch was the only application I had open. If by chance it's not in the attached datadumps, I'm trying the 20180410 xubuntu bionic daily build.
Update: this also occurred after installation failed. These problems may be due to the usb drive, made with Rufus on Win 7. I haven't had so many problems using linux-made drives.
