Comment 2 for bug 348006

I updated Ubuntu with the latest unofficial patch on Till Kamppeter's site, and now it's 'kind of' working again, at least I get to print a test page...
But I had to remove the printer, and install it again manually, because the autoinstaller could'nt find a valid model name.
Here is my syslog from that session:

First, I deleted the printer, then powered it off, and then on. And here the log begins:

Then I chose to add the printer manually, and the model name turned up in the list automatically (R300), so I chose it.
Here is the syslog after that:

To me, it looks like there is some kind of bug in the model name recognition code.
Anyway, I tried the same procedure yesterday, and was still unable to print a test page (gs segfault again), so something must have been fixed in the unofficial beta code.
