Internal Trac error in displaying timeline data

[geoffrey@…]

I have Trac setup using mod_python on a Gentoo server. The installed version of Python is 2.3.5. and the installed version of Subversion is 1.2.3. Whenever I click on the hyperlink for timeline, I get errors. However, refreshing the page two or three times resolves the issue and then the timeline data eventually gets displayed. The error I get is:

'module' object has no attribute 'apr_initialize'

with a Python traceback of:

Traceback (most recent call last):

File "/usr/lib/python2.3/site-packages/trac/ModPythonHandler.py", line 195, in handler

core.dispatch_request(mpr.path_info, args, mpr, env)

File "/usr/lib/python2.3/site-packages/trac/core.py", line 439, in dispatch_request

module = module_factory(args, env, database, req)

File "/usr/lib/python2.3/site-packages/trac/core.py", line 175, in module_factory

pool, rep, fs_ptr = open_svn_repos(repos_dir)

File "/usr/lib/python2.3/site-packages/trac/core.py", line 452, in open_svn_repos

core.apr_initialize()

AttributeError: 'module' object has no attribute 'apr_initialize'

I'm really not certain if this is a timeline related problem, or a mod_python issue.

I know this one!

Its a subversion problem. I had something simular when I installed subversion trunk (1.3.0-dev), going back to 1.2 fixed things.

(except i wasn't using mod python)

yes, it has to be svn. we have python 2.3.5, mod_python, subversion 1.1.3 with trac 0.8.4 running on a gentoo server without that error.

I had this problem, i tryed python-updater, and just after upgrade mod_python, and solved the problem.

This problem was certainly due to the SVN python bindings that were not correctly installed.

For better error reporting in the timeline, see #2346.
