I encountered the same symptom a few months ago, it was transient.
Today, a crash occurs every time I attempt to take a snapshot.

I have a vlc.core file (246.4 MiB) but don't know how to parse it for bug report purposes.
I cannot reproduce this here. Looking at google, this is however something that has already been reported elsewhere for the past few years.
