Actually IBrowse 1.22 is very stable and not so much different from IBrowse 2.x series. It lacks Javascript and tabbing and crashes in low mem situations but generally it never crash. Too bad there are no websites IBrowse could display properly at this age...
You are probably right about IBrowse 1.22, I actually made a mistake thinking I was using 1.22 all this time, but it's only 1.2. So it's actually IBrowse 1.2 that comes for free on Aminet CD 24, not 1.22. Unfortunately I can't find 1.22 or an update online anywhere, although it definitely was the last 1.x version.
The problem people are most-likely having with AWeb crashing are the Datatypes they're using. Do some tests to see which type of images are causing the crashes (JPEG/GIF/PNG) and try some replacement Datatypes for those.
