Bug#715052: qgis: Could not load PyGIS - sip version mismatch

[Russell Edwards]

Package: qgis
Version: 1.7.4+1.7.5~20120320-1.1+b1
Severity: important

Dear Maintainer,

I installed qgis from jessie, on an up-to-date jessie-amd64 system 
and received the following error in a dialog box:

Couldn't load PyQGIS.
Python support will be disabled.


Traceback (most recent call last):
  File "", line 1, in 
RuntimeError: the sip module implements API v10.0 but the qgis.core module requires API v8.1


Python version:
2.7.5+ (default, Jun  2 2013, 13:28:26) 
[GCC 4.7.3]

QGIS version:
1.7.5-Wroclaw 'Wroclaw', exported

Python path:
['/usr/share/qgis/python', '/home/redwards/.qgis/python', '/home/redwards/.qgis/python/plugins', '/usr/share/qgis/python/plugins', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PIL', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/pymodules/python2.7']

QGIS then opens up with reduced functionality. I'm new to QGIS but it seems
like some faily important aspects are disabled due to this issue.

Googling reveals others experience similar issues - I imagine the solution
would be to adopt a later version of QGIS.
