Internal error when trying to download anything

[i0ntempest]

When trying to download anything from the Apple developer page I get a message saying an internal error occurred. If I choose continue then aria2 keeps running and downloads just fine, if I choose crash then aria2 also keeps running but crash reporter does not pop up.
Copied from the error window:

Exception Name: NSInternalInconsistencyException
Description: Completion handler passed to -[Downloader.DownloaderViewController webView:decidePolicyForNavigationAction:decisionHandler:] was called more than once

I just noticed this dialog pops up because I enabled "Display dialogs for uncaught exceptions" enabled for crash reporter. If this is not considered a bug feel free to close.

Fixed in the latest release.
