Googling, it seems that several people (on various other distros) have
had similar problems. Various different causes are suggested but there
doesn't seem to be any definitive response.

The most believable response says that it is a problem with wxGTK not
working with gtk+ >=2.11 "since it moved to using GSlice for
GtkBorder.  calling g_free results in a double free corruption.  see
/usr/portage/x11-libs/wxGTK/files/wxGTK-2.6.4.0-g_free.patch"

I'm still not sure why that would cause cause crashes most but not all
times.

Others suggest ffmpeg issues.
