Hi, I had similar problems. On my machine the new libc5 version of netscape would also immediately crash with a bus error. I solved this on seeing your mail by moving my ~/.netscape to some other directory. However, I do not use xswallow, so it is problably some more general problem with netscape. This also partially answers my own mail about problems with the libc5 version of netscape.
I also tested the libc5 version of netscape on slink (sharing /home and therefore also ~/.netscape). This also gives a bus error. However, the ldd output is different on slink and potato. On potato is says it does not find libg++.so.27 and libstdc++.so.27, it uses both libc5 and libc6 and it uses the X-libraries from /usr/X11R6/lib. On slink it does find libg++.so.27 and libstdc++.so.27, it only uses libc5 and it uses the X-libraries from /usr/lib/libc5-compat. The behaviour on slink looks better to me, but I do not know if the behaviour of potato is really wrong. It does seem to work after getting rid of ~/.netscape. Hope this helps somebody to further clarify this. I am still puzzled. Christian van Enckevort
