Are you sure you have different versions of therion and therian-viewer
(loch)? This page says they should be the same for natty:
http://packages.ubuntu.com/search?keywords=therion&searchon=names&suite=natty&section=all

(5.3.3-1ubuntu1 for both).

I'm not sure if mismatched versions is a problem here - I guess things
should work anyway

That seems plausible. something horrid going wrong in the bowels of
wxwindows libs. That may just be loch tickling a bug, rather than
there actually being anything wrong with loch itself. 

I failed to find any matching bug already reported in Ubuntu or Debian.

I guess that means that you are using the proprietary nvidia drivers?

You could see if the free drivers work any better for you (noveau).
(They tend to crash my work natty X-server on a regular basis unless
one turns turn acceleration off). 

Finding out if therion 5.3.7-1 exhibits the same problem or not is of
course interesting. That is currently avaialble for oneiric. 

I've prepared a 5.3.8-1 now too. I'll put that in my PPA soon, pending
resolution of the therion.ini linefeed issue.
