I've tried running trac-admin /path_to/trac resync with apache2 stopped, also removed plugins and eggs cache in /var/www/.python… neither worked. Running gdb $(which python) followed by run /usr/bin/trac-admin /path_to/trac resync returned
(no debugging symbols found) Program received signal SIGSEGV, Segmentation fault. ---Type <return> to continue, or q <return> to quit--- [Switching to Thread 47407057438448 (LWP 12824)] 0x0000000000418f22 in ?? ()
Is there any more info I could provide?
Thanks.

bt? (in order to get a full backtrace)
See TracTroubleshooting for more GDB advice.
But in the end, it will probably be a mismatch in the libraries used, so also to a info shared
within gdb.

Thanks for such a quick reply. I've tracked down the problem to postgres connection. E.g. trying to create a new environment with a postgres backend would cause the same segmentation fault. The existing trac instances work w/o probs though (e.g. i can create tickets, modify wiki, etc.) I use *python-pgsql* that comes with ubuntu feisty and it didn't cause any troubles in the past. Here is the output of bt:

Well, apparently psycopg2 is also installed, and this gets used first (/usr/lib/python2.5/site-packages/psycopg2/_psycopg.so
).
If possible, disable temporarily psycopg2 and try again, it should then pick up pgsql.
Another possibility would be to upgrade psycopg2. Maybe the one you're using was built against the wrong version of postgresql.
comment:7 by , 17 years ago
Thanks, I purged python-psycopg2 and now trac-admin works like charm. Could you please advice whether python-psycopg2 or python-pgsql would suit Trac best? Many thanks for helping sort the issue out!

Well normally both should work. I think jonas is using psycopg2 here on t.e.o, and for my testings on Windows (admittedly superficials), I use both of them and never saw a difference. Perhaps you can find more details in DatabaseBackend.
comment:9 by , 17 years ago
This was actually a bug with psycopg 2.0.5 and python 2.5 on 64-bit systems, see https://bugs.launchpad.net/ubuntu/+source/psycopg2/+bug/108067 and psycopg:#167.
Worked for me with psycopg 2.0.6.
Well, you could try to disable all the plugins, at first.
You'll probably need to run
trac-admin
withgdb
to see which call triggers the crash.
