Subject: [PATCH] virLogCleanerShutdown: Don't call g_regex_unref on NULL regex
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Shutdown of virtlogd prints:

  (process:54742): GLib-CRITICAL **: 11:00:40.873: g_regex_unref: assertion 'regex != NULL' failed

Use g_clear_pointer instead which prevents it in the NULL case.
