banshee自动关闭 about banshee-doubanfm HOT 6 CLOSED

你好，

由于程序中对于异常情况处理不完善，这个错误有可能发生��
�登陆失败或者来回切换插件的情况下。能否告知以下几点：
1. 
是运行后显示“载入频道”，然后载入完成显示频道列表后��
�击任意频道崩溃吗？
2. 
载入频道列表后豆瓣电台插件处于激活状态吗（左侧栏目里��
�豆瓣电台”黑体显示）？

谢谢！

我也出现了上述情况

豆瓣电台无法主动显示出任意频道
如果我切换到别的插件再切换回来则可以显示出所有频道

我在任意情况下双击豆瓣电台，也会导致电台关闭

豆瓣电台插件处于激活状态，豆瓣电台黑体一直显示，并且��
�切换到其他插件上后，黑体仍然一直存在

谢谢指出问题，原因是从服务器获取电台列表和豆瓣登录是��
�时进行的，但是只有登录成功后才显示列表。如果成功获取�
��台列表但是登录却失败或者超时，就无法显示出列表。切换
到其他插件然后切换回来时没有考虑到登录失败的情况，直��
�把电台列表显示出来了，此时播放则由于没有登录成功而出�
��退出。我会尽快修正，谢谢。

麻烦你了～如果需要做任何测试～请随时发邮件给我～我会��
�力配合～～

版本库里的最新版已经修正了以下问题：
* 
登录失败而无法显示任意频道。新版里如果登录失败会有提��
�。
* 
因为需要验证码而无法登陆。新版里需要验证码的时候会弹��
�验证码输入窗口。
* 
切换到其它插件然后切换回来显示所有频道。新版里如果登��
�失败，则不会显示频道。
* 双击豆瓣电台异常退出

再做一些测试后会打包上传。
