No, those errors are nothing to do with the PR1.2 issues. I'd suggest disabling all your repositories, exiting App Manager, then going back in and re-enabling them again. That should force a redownload of all the metadata, hopefully fixing the corruption issue you appear to have.
i disabled all the repositories and then enabled them again but stil got the same error message in the log..
and when i go to my catalogues the maemo.org catalogue says "failed to refresh".
man i hope the PR 1.2 issue fixes this...
this sucks.. i don't have a single app on my n900..
im facing the same problem iv tried to go through every forum blog but cudnt get a decent answer
its says in my log, unknown date format, failed to fetch repository
and if i try to download a installer file on my laptop n transfer it to my phone n try to install it,it says application package not found and again th same list of errors
