I had pretty much the same crush problem with Ibrowse 2.4 on my 1200 030 / 16mb ram / OS 3.9, ages ago. It crushed when I tried to log in into one specific site (!!!!), it crushed for reasons unknown to me cause there was a time that I was able to visit this site as well with no probs. On other sites I tested -not that many after all and there were all Amiga sites-, Ibrowse worked well.
Problem fixed when I deleted the Java plugin from the plugins folder. I need to re check this stuff and perhaps re install Ibrowse -had done it back then but the problem remained-, but this Amiga is temporary off line.
Strange Amiga issues....
