1350059 - Response tab panel in network monitor doesn't render sometimes

Status: NEW

(DevTools :: Netmonitor, defect, P3)

Description

[Michael Hoffmann]

The Response panel doesn't render when looking at the POST request generated by the attachment for Bug 1344511, https://bug1344511.bmoattachments.org/attachment.cgi?id=8843629.  When clicking the Response-tab, whatever that is rendered in the panel below stays, as a re-render is not performed.

It won't render because of a "TypeError: mimeType is undefined" on this line
http://searchfox.org/mozilla-central/source/devtools/client/netmonitor/shared/components/response-panel.js#121

and `mimeType` is explicitly set to undefined here
http://searchfox.org/mozilla-central/source/devtools/shared/webconsole/network-monitor.js#607

For some reason, for that particular POST, `this.request` does not implement(?) the required interface.  `nsIChannel` I believe.
