PHP Errors related to cloudflare plugin

I run my site http://supriyosen.net on Hostpapa.

Recently, I turned on WP_Debug and found a number of “errors” reported. Some are:

[18-Oct-2013 21:37:27 UTC] PHP Notice:  Trying to get property of non-object in /home/xxx/public_html/wp-content/plugins/cloudflare/cloudflare.php on line 284
[18-Oct-2013 21:37:27 UTC] PHP Notice:  Trying to get property of non-object in /home/xxx/public_html/wp-content/plugins/cloudflare/cloudflare.php on line 285
[18-Oct-2013 21:37:27 UTC] PHP Notice:  Trying to get property of non-object in /home/xxx/public_html/wp-content/plugins/cloudflare/cloudflare.php on line 286
[18-Oct-2013 21:37:27 UTC] PHP Notice:  Trying to get property of non-object in /home/xxx/public_html/wp-content/plugins/cloudflare/cloudflare.php on line 287

This notice is repeated many times.

Is this indicative of a problem?
