[Python-apps-team] Bug#676176: trac: Unable to show changeset : TypeError: expecting an integer for the buffer size

[Eric Valette]

Package: trac
Version: 0.12.3-1
Severity: normal


   I have upgraded a working trac 11 installation to a track 12. 
Track is correctly working. I can browse subversion repostory and so
on. BUT I cannot see chnagesets.

When trying to see a diff for a file between two revision I have an 
internal error related to python handling of chnagelog parsing:

TypeError: expecting an integer for the buffer size

Googling on return only very old errors that depends from the trac.ini setup. But I
already double checked my config (and the value are the same than on previous setup).
