+Subject: [PATCH] Workaround concurrency issue
+
+There is a concurrency issue between rsvg plugin and it parent's
+class: videofilter.
+Because of this issue, the plugin crash because it tries to write
+a read only buffer.
+
+Until we find a proper way to prevent the concurrency, use this
+workaround to avoid the segfault.
