Aside from the fact that this issue is filed on the pharo instead of the
moose bugtracker
14858 <https://pharo.fogbugz.com/default.asp?14858> Hangup when rendering
TRLabelShape with SmallInteger instance as text
I wonder why the error locks the UI.
I can see a RMOD, maybe Trachel should stop any attempt for rendering
if the Morph has the #errorOnDraw property set?
