Package: pyspread
Version: 1.1-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

With the latest apt-get upgrade, the spreadsheet canvas of pyspread will
no longer show, instead it's just a white box without the grid.  This
makes the pyspread package unusable.  The console is full of error
messages like the following:

Traceback (most recent call last):
  File "/usr/share/pyspread/src/gui/_grid_renderer.py", line 340, in Draw
    grid._view_frozen)
  File "/usr/share/pyspread/src/gui/_grid_renderer.py", line 263, in 
_get_cairo_bmp
    context = wx.lib.wxcairo.ContextFromDC(mdc)
  File "/usr/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/lib/wxcairo.py", line 
137, in ContextFromDC
    ctx = pycairoAPI.Context_FromContext(ctxptr, pycairoAPI.Context_Type, None)
AttributeError: 'Pycairo_CAPI' object has no attribute 'Context_FromContext'

I am not sure what caused this problem, but am now seeing this on
several machines, and believe it to be universal.  To reproduce it,
simpy start pyspread (with no spreadsheet file at all).

Judging from the error messages, the bug might not be in the pyspread
package, but in some package it depends on.

I don't know a workaround for this problem.
