This is now a release-critical issue in Debian, and therion is going
to get thrown out if we can't fix it.

therion 5.3.14-1 is marked for autoremoval from testing on 2014-06-27
It is affected by these RC bugs:
749687: therion: Please update to use wxwidgets3.0

Stacho - I think you understand loch - can you find some time to look
into this and see what we need to do to make it work properly (does
wx3 work on Windows?, do you have access to a Debian machine?)

(And looking at VTK6 would be good too, although I'm not actually
completely stuck there yet).
