    <thetext>WebKitGTK crashes when attempting to drag-and-drop files into websites that support file uploads (WhatsApp Web and others). The crash occurs consistently across all websites with file upload functionality.
The crash occurs in WebKit&apos;s IPC layer during drag controller operations:

Messages::WebPage::PerformDragControllerAction
IPC::Connection::makeAsyncReplyCompletionHandler

The crash happens when the main process attempts to communicate with the WebKit process to handle the drag-and-drop action, but something fails in the async reply completion handler.

WebKitGTK 2.50.1

    <thetext>Very likely this is a duplicate of 299208. It&apos;s more convenient to follow a single report, so I&apos;m closing this one.

    <thetext>Note: since you selected &quot;New Bugs&quot; instead of &quot;WebKitGTK&quot; it could have been months or years before somebody noticed and reassigned this. Be careful to select the WebKitGTK component or we won&apos;t see it!</thetext>
