Yeah I'm not sure if there are any drawbacks! After removing wxagg, 
matplotlib *seemed* to work just fine.

I didn't make any other changes. I assume it has something to do with 
other packages that I have installed. But wxPython and wxGTK3 are on 
both my Slackware current installs and only one shows this issue. I just 
realised that in my initial email, I forgot to say that this happened on 
*current* not 14.2, so feel free to ignore this request on that basis!

Thanks for looking at this!
