I just updated from master branch and I get

library(dplyr, warn.conflicts=FALSE)
phoible_col_types <- readr::cols(InventoryID="i", Marginal="l", .default="c")
phoible <- readr::read_csv('phoible.csv', col_types=phoible_col_types)
phoible %>% select(InventoryID, Phoneme) %>% group_by(InventoryID, Phoneme) %>% filter(n()>1)
# A tibble: 0 x 2
# Groups:   InventoryID, Phoneme [0]
# … with 2 variables: InventoryID <int>, Phoneme <chr>
