Re: Hans? Can you review this? Re: Dia freeze up

[Hans Breuer <hans breuer org>]

Michael et al.,
sorry for top-posting, but here is a brief summary:

 - in my experiments I only had freezes (endless loop) with
   the cairo renderer, so a diagram to reproduce would help
 - I don't understand what 'process tree' you are killing
 - there is no mechanism in standard Dia deleting the log file
 - the log file name is 'dia--0.97.2.log' (just typos in your
   message and may be hidden extensions in explorer?)
 - there indeed is a bug in Dia 0.97 with rounded polyline
   drawing; fixed on master if anybody wants to backport [2]
 - only workaround for 0.97.x is avoidance of rounded polylines
   or their arc degeneration

HTH,
        Hans
