** Description changed:
While I was trying to update a system/profile definition, I got hit by
the backtrace below. Given the last line in the backtrace suggests this
is an error in a 'distro' instance, I went and edited the disto
affected: same error.
I then tried _other_ distros, and they also failed (but I did not try
all). This was working as of 2.1.0+git20110602-0ubuntu26, ergo I suspect
a regression.

+ [SRU REQUEST] - ONEIRIC
+
+ [Impact]
+ If am image is found, during PXE setup, the process may abort with the
backtrace above. When this happens, no updates or usage of the affected
profiles/systems is possible anymore, effectively disabling Cobbler.
+
+ [Development Fix]
+ A fix has been written by Scott Moser, and uploaded to precise; an upstream
merge has been requested (https://github.com/cobbler/cobbler/pull/94)
+
+ [Stable Fix]
+ A fix to Oneiric has been proposed; this fix is slightly different from
upstream due to changes in the code from 2.1 to 2.2.2 and GIT. A package has
been built on a PPA (https://launchpad.net/~smoser/+archive/ppa) to field-test
it; this same fix has already been deployed on personal package build my C
de-Avillez.
+
+ [Text Case]
+ -- BEFORE applying the fix:
+ 1. You MUST have images on your Cobbler install, and MUST try to update a
profile/system with images.
+ 2. Edit the profile/system;
+ 3. Click on the SAVE button at the bottom.
+
+ FAILS -- an error is shown, and the /var/log/cobbler/cobbler.log shows a
+ backtrace as above;
+
+ -- AFTER applying the fixed package, and AFTER restarting Cobbler:
+ Repeat steps (1)-(3) above.
+ SUCCEEDS -- the save completes with no errors.
+
+ [Regression Potential]
+ Patch is isolated, straightforward, and affects only the code path in the
backtrace.
+
+ [Original Report]
+ This is it. Additionally, there is
https://github.com/cobbler/cobbler/issues/16 upstream.
