On the search engines state for the new about:home, we can reach a state where the search shortcuts pane is completely blank. STR: 1. Type into search bar to bring up search shortcuts. 2. Scroll on the search shortcuts (this dismisses the keyboard). 3. Tap on the menu bar; this highlights the text and brings up the keyboard. 4. Start typing. Expected: Search shortcuts pop up to match the entered text Actual: Entire pane goes blank, see screenshot. Note: Dismissing the keyboard via the back key and starting to type again does not cause this problem.
I'm not able to reproduce, maybe others can? Sounds bad, tracking?

I can't reproduce this either, but I'm seeing a terrible glitch when the keyboard dismisses where it looks like we draw the list of search suggestions twice momentarily :/
I am able to reproduce this on Samsung Galaxy Nexus (Android 4.1.1) with SwiftKey keyboard. I will try to find a regression range.
Regression window-wanted: There are three builds in 08/21 central, when fig has been pushed to m-c. The first build is not affected and the second one is affected. The pushlog is: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=d136c8999d96&tochange=b2486721572e
... so new-about-home

It would be nice to know what changed between the first and second builds.
The first build from 08/21 is unaffected and it is with the old about:home. The second build from 08/21 is the affected one, with the new about:home

Jim - Are there any gotcha's with swiftkey we should be looking for? Can you look at the logs for any issues?

I did some logging. When typing to replace existing, selected text, SwiftKey deletes the selected text first, before committing new text. This is different from the stock keyboard behavior which commits the new text directly and relies on the editor to delete the old text. For example, if the current text is "foo" and selected, SwiftKey will call DeleteText(0, 3) then InsertText("bar"), whereas the stock keyboard only calls InsertText("bar"). The result is the same but SwiftKey makes an extra call. In SwiftKey's case, the text field is temporarily blank due to the DeleteText call, so maybe that messes up the search code.
As Jim said, SwiftKey deletes the text before committing new text. This triggers hideBrowserSearch() since the text is empty, then showBrowserSearch() immediately after for the committed text. When this happens, the container given to BrowserSearch#onCreateView is null. I assume this is an Android bug, and I filed it as http://code.google.com/p/android/issues/detail?id=61179. Calling FragmentManager#executePendingTransactions seems to work as a workaround.
