[Pkg-trac-devel] Bug#519670: trac: Trac can't synchronize with SVN repository

[Quinn Li]

Package: trac
Version: 0.11.1-2.1
Severity: important

I recently upgraded my Debian system from Lenny to Squeeze. Now Trac website displays a warning message on the top of every page:

    Warning: Can't synchronize with the repository (Unsupported version control system "svn": "/usr/lib/libsvn_ra_serf-1.so.1: undefined symbol: apr_file_buffer_set" ). Look in the Trac log for more information.

Also 'Timeline' and 'Browse Source' tab shows an error:

    Repository checkins event provider (ChangesetModule) failed:
    TracError: Unsupported version control system "svn": "/usr/lib/libsvn_ra_serf-1.so.1: undefined symbol: apr_file_buffer_set"

trac.log contains following messages:
