Ah, ok thanks Michael - I'd found that bug from some googling, but
Doug's comment here:
http://groups.google.com/group/turbogears/msg/26d74c947dec400e
implies that it was fixed in Python 2.5.2 (I'm using 2.5.4 - sorry I
forgot to include that). However, the comments on the official Roundup
bug say it can't be backported from 2.6 after all...
Looks like I'll be using 0.4.3 until TG supports 2.6!

this is a known Python issue fixed in 2.6.

I'm using SA underneath a TurboGears 1.0 app. Upgrading SA from 0.4.3
to 0.4.4 causes previously passing unit tests to fail when run in
conjunction with nose's coverage plugin -- I've included an example
stack trace below.
The unit tests run just fine when not using nose's --with-coverage
option.
The only other useful information I have is that some basic logging
shows that more of my model code is being run under 0.4.4 than under
0.4.3, when using coverage.
I don't have a small reproduction, nor have I looked at this in lots
of detail - before I do, is this a known issue, or does it can anyone
suggest a good place for me to start debugging?
Thanks!
