Description:I create channel via ARI with the next data:
{ app: 'Queue',
 endpoint: 'Local/skynet.device-1900@queue_members.dial',
 channelId: '1651f065-c45e-4dbc-b187-ca97eb1caf5b.testqueue.74' }

ARI sends me successfull response body:
{"id":"1651f065-c45e-4dbc-b187-ca97eb1caf5b.testqueue.74","state":"Down","name":"Local/skynet.device-1900@queue_members.dial-00000047;1","caller":{"name":"","number":""},"connected":{"name":"","number":""},"accountcode":"","dialplan":{"context":"queue_members.dial","exten":"skynet.device-1900","priority":1},"creationtime":"2014-08-27T00:22:07.653+0000"}

Then I add channels to existing bridge:
/bridges/b1cc1a44-0091-49db-ad62-97d165d70c05/addChannel
{ channel: '1651f065-c45e-4dbc-b187-ca97eb1caf5b.testqueue.74,1409098921.725' }

After that I start to receive strange events with ;2 everywhere:

ws received: {"type":"ChannelDialplan","dialplan_app":"Set","timestamp":"2014-08-27T00:22:07.672+0000","dialplan_app_data":"QUEUE=testqueue.74;2","channel":{"id":"1651f065-c45e-4dbc-b187-ca97eb1caf5b.testqueue.74;2","state":"Ring","name":"Local/skynet.device-1900@queue_members.dial-00000047;2","caller":{"name":"","number":""},"connected":{"name":"","number":""},"accountcode":"","dialplan":{"context":"queue_members.dial","exten":"skynet.device-1900","priority":1},"creationtime":"2014-08-27T00:22:07.660+0000"},"application":"Queue"}

This is not a bug.

You are creating a Local channel. That always creates two channels. Since you failed to provide another channel ID for the second half of the channel, Asterisk added the ';2' - otherwise, you'd have two channels with the same ID, which wouldn't work very well for your application at all.

As noted in the ARI documentation, you need to use the {{otherChannelId}} field:

{quote}
otherChannelId: string - The unique id to assign the second channel when using local channels.
{quote}

In the future, you should raise your questions on the {{asterisk-app-dev}} mailing list. Based on the description of your issue, I think you will have more questions about how Asterisk works with Local channels, and how the subscription model of ARI works. Rather than deal with this on the issue tracker - which is *not* a support forum - future questions should be directed to that mailing list.
