FWIW I have ran into the same issue while testing demos of psychopy
so if you want to reproduce, just apt-get install psychopy and run python /usr/share/pyshared/psychopy/demos/coder/timing/timeByFrames.py whenever you see red bar growing press some key (e.g. space) -- you should experience segfault whenever the script tries to work with matplotlib, Bug gets "preconditioned" by imports from psychopy -- if there is no imports from psychopy, script (having commented out relevant part) seems to plot fine. -- =------------------------------------------------------------------= Keep in touch www.onerussian.com Yaroslav Halchenko www.ohloh.net/accounts/yarikoptic -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
