Bug 97890 – Web Inspector: Profiles: taking heap snapshot causes error message in console.

• Status: RESOLVED
• Resolution: FIXED
• Component: Web Inspector (Deprecated)

Actual problem is that proxy loader is closed twice.

"_snapshotReceived" should never try to close receiver,
because it is a callback fired by close.

Also minor glitches fixed:
 - taking snapshot shows "Loading..." status first,
and then "Saving xxx%";
 - after all chunks are sent "Parsing" status is set and
then is replaced with "Saving 100%";
 - "Loading %d\%" is not localized.

We prefer localizeble string literals always to be within UIString(), even if it may be a bit more code.
Also, now that this handles both saving and loading, I think the method could be renamed to something more generic.

Can we reuse saveStatusUpdate() here?

Should it be (0, this._totalNumberOfChunks) ?
