Hi,

I'm in OSX 10.10 and is facing the following problem. First I import PyPlot by 'using PyPlot' and plot some stuff, it works. Now if i call a workspace() and try 'using PyPlot', julia crashes. Below is a sample log

Perhaps not 100% the solution you're looking for, but ClobberingReload.creload is a reload alternative that bypasses (most of) the need for workspace().
