Subject: Reset magick_list_initialized when needed
X-Git-Tag: 7.0.7-6~4
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8bd5053430a0343dac1f5bf103de736d23f974e7;p=imagemagick

Reset magick_list_initialized when needed

Failure to do so makes it impossible to re-init magick_list as it is already
marked as initialized even if it was destroyed.

Fixes #825.
