Would it be possible to give a more informative error message here?

> z <- "abcdef"
> select(data_frame(x=c(1,2,3)), z)
Error in abs(ind[ind < 0]) :
   non-numeric argument to mathematical function

Also for

> data_frame(x=c(1,2,3)) %>% filter(F) %>% select(x)
Error in (function (classes, fdef, mtable) :
  unable to find an inherited method for function ‘select’ for signature ‘"data.frame"’

I get this same error when the raster package is loaded. One workaround is data_frame %>% dplyr::select(x), but I don't want to have to restart R and change package loading order every time I happen to need a package with a "select" function that clashes with dplyr's. Will the bug fix address this?
