fails to remove in maverick

[Michael Vogt]

TEST CASE:
1. install python3-jinja2 in maverick
2. uninstall python3-jinja2
3. verify that it fails
4. install python3-jinja2 from maverick-proposed
5. uninstall python3-jinja2
6. verify that it works now

During a automatic maverick->natty upgrade the auto-upgrade tester found the following problem:
...
Removing python3-jinja2 ...^M^M
+ find /usr/lib/python3.1/dist-packages/jinja2/ -name *\.pyc -delete^M
find: `/usr/lib/python3.1/dist-packages/jinja2/': No such file or directory^M
find: `/usr/lib/python3.1/dist-packages/jinja2/': No such file or directory^M^M
dpkg: error processing python3-jinja2 (--remove):^M^M
 subprocess installed pre-removal script returned error exit status 1^M^M
...

The reason for the failure is that the path in the prerm scrip is incorrect:
-find /usr/lib/python3.1/dist-packages/jinja2/ -name '*\.pyc' -delete >/dev/null
+find /usr/lib/python3/dist-packages/jinja2/ -name '*\.pyc' -delete >/dev/null

this was changed in 2.5.2-3 (after a change in python3.1 package in Debian)

PS you REALLY should consider adding package version numbers to bug
reports.

Accepted jinja2 into maverick-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

I've followed the test case and can confirm that the bug is fixed with the proposed package (package gets removed), marking this as verification-done, thanks all.

[Launchpad Janitor (janitor)]

This bug was fixed in the package jinja2 - 2.5.2-2ubuntu1

jinja2 (2.5.2-2ubuntu1) maverick-proposed; urgency=low

  * python3-jinja2.prerm:
