helm-baidu-dict-suggest报错，奇怪啊

uncompressing publicsuffix.txt.gz...done
error in process filter: url-http-parse-headers: Transfer interrupted!
error in process filter: Transfer interrupted!

尽量一次性输入所有查询词，一个字符一个字符慢慢输入会有很多网络请求，出错不奇怪，用户输入中间本应加点延迟的，不过我不清楚怎么操作。

我不是慢慢输入的，我是快快输入的，确实无法查询

这个要是集成到pyim会不会很酷
