Off the top of my head, the recent (a few months back) multi-block fork during which some SPV clients were on the "wrong" chain comes to mind. I certainly wouldn't want my client telling me something which later turns out to be different. While the situation may not turn out to be directly damaging as far as a user's funds go, confusion itself can certainly lead to various problems resulting in actual damage.

But that is not the case for Electrum since is not truly an SPV wallet,because it only connects to electrum servers not bitcoin nodes(and altcoins such as Bitcoin XT)
Same could be told about a couple mobile wallets(such as Mycelium)that connects to a couple of centralized nodes and which are less affected by what you described and a couple of sybil attacks that ("real")SPV wallets are affected by it
