Unfortunately I cannot reproduce the issue. So please try again with 2.2.8 and
provide the output of vlc -vvv.

Bug#813545: vlc: freeze followed by segmentation fault after closing the window
Package: src:vlc
Version: 2.2.2-1
Severity: important
After I close the window, VLC froze then crashed (segmentation fault).
I could reproduce this problem another time, but that's all. This never
occurred with previous versions.
Program terminated with signal SIGSEGV, Segmentation fault.
