R session hangs up after using ggplotly()

Question

My R session (within RStudio) hangs up after using ggplotly().
For testing, I use one of the examples of ?ggplotly. The example normally works ok once or twice, but the R session hangs up after several tries (in the example below, the 2nd run hung up the session). I cannot even close the RStudio from the GUI and have to use the System Monitor application to kill it.
This problem arises when I run the following code after I have loaded a given project, not if I start a R session with no project. But the project does not load any data or package, so do not know how to identify the problem.
This is what I specifically do:

I have found that loading package TSclust is the problem:

require(ggplot2)
require(plotly)

    data(canada.cities, package = "maps")
    viz <- ggplot(canada.cities, aes(long, lat)) +
    borders(regions = "canada") +
    coord_equal() +
    geom_point(aes(text = name, size = pop), colour = "red", alpha = 1/2)
    ggplotly(viz, tooltip = c("text", "size"))
    #check that works
    #clear all Viewer panes with the button
    require(TSclust)
    ggplotly(viz, tooltip = c("text", "size"))
    #no View and R hangs up
