Ok, I guess this is embarrassing, but as I was trying James' workaround in #92 , I started thinking that somehow the signal was weak or intermittent. A few minutes later, Solaar (the GUI that displays status of Logitech wireless devices) tells me that the battery level in the mouse was down to 5%. I replaced the only battery it takes (I have the M215), and the middle button started working just fine.
It's been rock solid for a few days.Running Bionic now.
(as an aside, it seems like the battery reporting capabilities are not too good: new batteries show 90% charge, and this one "dropped" from 90% to 5% instantly. But the battery was very likely almost empty for quite some time)
