FIY, with the help of Sylvestre Ledru (debian atlas maintainer), the
problem was solved installing libatlas3g-sse*.

I notice that the illegal instruction does not occur when the figure
does not contain any axes.

Here is the backtrace:
(gdb) run test_plt.py 
Starting program: /usr/bin/python test_plt.py
[Thread debugging using libthread_db enabled]
/usr/lib/pymodules/python2.5/matplotlib/backends/backend_gtk.py:621: 
DeprecationWarning: Use the new widget gtk.Tooltip
  self.tooltips = gtk.Tooltips()

Program received signal SIGILL, Illegal instruction.
0xb767b638 in ATL_diamax_xp1yp0aXbX ()
from /usr/lib/libblas.so.3gf
(gdb) bt
#0  0xb767b638 in ATL_diamax_xp1yp0aXbX ()
from /usr/lib/libblas.so.3gf
#1  0x in ?? ()
(gdb)

Surprisingly, the troubles come from libblas. In fact, I daily update my
debian and, on wednesday, the package libatlas3gf-base has been updated
from 3.8.3-21 to 3.8.3-22. It seems that it had some side-effect on
matplotlib behaviour...
But why does the interpreter crash only when the pointer enters the
figure canvas??

Can you get a gdb backtrace?

(Run "gdb python", then "run name_of_script.py", cause it to crash, and 
type "bt" in gdb console...)

[Matplotlib-users] Matplotlib crashes on mouse event

2010-05-13 Thread Fabrice Silva 
hi folks,
even on simple script, matplotlib crashes : 
fab:$ python
Python 2.5.5 (r255:77872, Apr 21 2010, 08:44:16) 
[GCC 4.4.3] on linux2 
Type "help", "copyright", "credits" or "license" for more information.
>>> import matplotlib.pyplot as plt
>>> plt.plot([4,2,8])
/usr/lib/pymodules/python2.5/matplotlib/backends/backend_gtk.py:621: 
DeprecationWarning: Use the new widget gtk.Tooltip 
  self.tooltips = gtk.Tooltips()
[]
>>> plt.show()
Instruction non permise

The crash occurs when the mouse enters (if previously outside) and moves
(if previously inside) in the figure.
I am using debian unstable package (0.99.1-1) and admit I have try to
manually modify the gtk backend to resolve the ginput bug (due to
changes in stop_event signature, solved by r8531 but not in debian
package). Since then the crash occurs automatically. Even a complete
remove/purge/install of the package does not solve the problem.

Any idea? Matplotlib's developers? Sandro (Debian maintainer) ?
