After upgrading to wordpress 2.0, I found the WP2.0 is failed to send trackback.

This issue is also confirmed by ijliao, priv, and Ah Knight’s Blog.

There has been a workaround in Ah Knight’s Blog for this issue.But even you clean up the “to_ping” field, you may encounter this issue again later. Instead of clean up the “to_ping” field times by times, I try to dig the bug out from the source.

把站台從 wordpress 1.5 升上 wordpress 2.0 的人們，可能發現不能 Trackback了。我，也中標了。

this problem is because of to_ping field contain some char ( including space, tab which represent by \n\r )

正好在 IRC 上，我跟 ijliao、priv也在討論這個問題，既然問題可能出在 to_ping這個欄位，於是乾脆進source裡翻翻看，看問題到底出在哪裡。

不翻則已，一翻嚇出一聲冷汗。
