Hi,
I'm using yade-bzr2612 on ubuntu 9.10. The plot window crashes at some point
almost in every simulation, regardless the simulation it's running.
When it happens in the terminal I got:
ERROR: An unexpected error occurred while tokenizing input
The following traceback may be corrupted or invalid
The error message is: ('EOF in multi-line statement', (550, 0))
ERROR: An unexpected error occurred while tokenizing input

134 y = self.figure.bbox.height - event.y()
135 button = self.buttond[event.button()]

1218 event = MouseEvent(s, self, x, y, button, self._key,
guiEvent=guiEvent)
-> 1219 self.callbacks.process(s, event)
1220 self._button = None
1221
...and continues with something similar for other a while (do you need the
whole output?)... and then:
KeyError: (0.0, 0.00019999999999999987, u'0.0002', 'k', 'center', 'right',
7623432979757281113, None, 80, 79854408)
At this point I close the window plot (with the simulation still running), and
open it again with the F8 command. Sometimes it works, sometimes I got:

RuntimeError: underlying C/C++ object has been deleted
Could it be related to the python version (Python 2.6.4 (r264:75706, Dec 7
2009, 18:43:55)
[GCC 4.4.1] on linux2) I'm using?
or do I need any other python package?
It's not that I can't run the simulation as it works now, but it's a bit
annoying.
Thank you
Giulia
