I have build 1.0.0.94391081, and I get the trash icon both when looking at individual photos and when selecting one or more photos. Which build do you have? (And which device?)
I have the same build! How strange. I'm on a Nexus 6 (stock 5.1.1), UK based but SIM-Free (not carrier branded). See my other comment for a screenshot of what I see.
It's frustrating as I have to click the menu button, then Delete, then OK. I used to just hit Trash icon and that was it. For one-off deletions it's only a little slower - for working through a days worth of shots (or worse, high speed drive shots transferred from my camera).
That is strange! I'm also on a stock 5.1.1 Nexus 6, but in the U.S. I guess you can at least be happy that this appears to be a bug (which means hopefully it will be fixed soon) as opposed to a bad design decision.
