"add-on Product" During Install Fails (core Dump Etc.)

First establish that I have good CDs:
Downloaded, checked MD5SUMs, burned, cmp xxx.iso /dev/hdd. CDs are good.

Began install, got through language etc. to screen asking what kind of install to do.

First problem (Minor, got by it):
"New Installation" has "Include Add-on Products from Separate Media" grayed out.
This was offered in 10.1 (not grayed) and worked fine.
Clicking "update" un-grays "Include Add-on...", Then clicking "New Installation" leaves it available.

Select "New Installation" and "Include Add-On Product from Separate Media"

Machine catalogs CD1, then puts up the "Add-On Product Installation" screen.
I click "Add"
Dialog asking me to select the media type comes up.
I click on "CD" and "Next"

Dialog asking me to "Insert the Add-On Product CD" comes up.

Second problem (Minor, got by it):
Pressing the eject button on the drive does not eject the install CD to enable me to
put in the Add-On CD. In 10.1, it did.
Clicking the provided "Eject" button on the GUI ejects the CD.

I put in the "Add-On" CD.
Click "Continue"

Third (MAJOR) problem:
>>> The above sequence was done multiple times. What happened next varied:

Example #1:
"Unable to create catalog from URL 'cd:///',
Details: Unknown source type for cd:///
Try again?

Example #2:
System freezes with mouse arrow roughly in middle of screen.
Mouse does not respond.
control-alt=F3 takes me to the system log.
"Segmentation Fault at SourceManager.ycp: 472"
>> Followed by many shell-script like errors, segmentation errors, core dumps.

Problem appears to be 100% repeatable in the sense that it never gets beyond this
point, although exactly what happens varies.

System HAD been running opensuse 10.1 for a few weeks before this.

Any help would be greatly appreciated. Can anyone get successfully beyond this
point with the 10.2 distribution CDs?

Problem solved. Opensuse requires a minimum of 384MB to install.

Installer needs 384MB (Started with 256, tried 320, 384, 512. 384 and 512 worked).

Installation instructions say that you may have trouble with less than 256 and a referred page discusses how to reduce memory requirements. Note that my problem occurred before I got into the details of the install, so the problem I think SHOULD occur on ANY attempt to install with 320MB or less. It was not dependent on any input from me specific to my installation other than language and accepting the license agreements.

I now have 512MB in the machine.

Confirmed on a second machine, both the problem with 256M, and that the problem does not exist with 512M.
