I assume this is because the text selection views aren't included in the gecko layout that web apps use, since this crash means that the handle views are null:
http://mxr.mozilla.org/mozilla-central/source/mobile/android/base/GeckoApp.java#1985

I'd think we just need to add the text selection layout to web_app.xml like:
http://mxr.mozilla.org/mozilla-central/source/mobile/android/base/resources/layout/gecko_app.xml#40
Attached patch patch (obsolete) — Splinter Review
This patch adds the text selection handle layouts to web_app.xml, but I also added a null check in the TextSelection constructor so that we won't crash if we run into this problem again with another GeckoApp instance (text selection just won't work in that case).

I'd like to move the shared stuff into one layout so that we (hopefully) don't have to keep dealing with this. Clearing review.
Attachment #644977 - Flags: review?(wjohnston)
The text_selection_handles layout is now only used in this shared layout. I feel like it's cleaner to keep it separate, but on the other hand it's nicer to minimize the number of XML files we have floating around. What do you think?

Actually, this doesn't need to be on beta because web apps aren't there. I landed it on aurora, though:
