Details

Since -5 version of the package, there is an error when I use certain features of the software.
For example when I click on the "preferences" menu and when I request a report Ancestor.

Preference menu

This errors don't look as python3 related. Moreover Reports -> Graphical Reports -> Ancestor Tree don't crash gramps on simple database with 2 persons.
Comment by Jan de Groot (JGC) - Thursday, 10 October 2013, 12:03 GMT
This is python related. Strings can either be ascii or binary in python3. If an ascii string contains unicode characters, python will give this backtrace and abort.

Maybe exporting db from python2 gramps version and importing it into current will help?
Comment by Panhaleux Michel (Mithrandir91) - Thursday, 10 October 2013, 13:42 GMT
Reloading a previous backup, the error on the preference menu no longer occurs, but the error on the "tree of ancestors" graphical report persist.
Comment by Jan de Groot (JGC) - Thursday, 10 October 2013, 13:58 GMT
Looking at the first trace, gramps stores the data as serialized objects. If that format changes between python versions (where python2 stores everything as binary where python3 has ascii, unicode and binary), then you'll get the error from the first trace.

The 2nd trace left is fixed upstream:

Could you still reproduce the problem with gramps 2:4.0.2-2?
Comment by Panhaleux Michel (Mithrandir91) - Monday, 20 January 2014, 15:46 GMT
I'm sorry but I did not keep the environment producing the problem.
I corrected the problem with the "tree of ancestors" by applying the patch indicated by Jan de Groot above.
Comment by Balló György (City-busz) - Monday, 20 January 2014, 15:54 GMT
The version 4.0.2 contains that patch, so I'm closing this task.
