Summary: disk error in icons crashes machine


Since I haven't heard this mentioned before, I thought I'd pass on
this bug: if there is a hard error on the diskette in the middle
of an icon, you get a guru. I don't have the number handy but it's
real reproducible....just open the window containing the bad icon,
and when workbench tries to read the icon, ka-blam!

Obviously workbench is not checking for errors, and it proceeds with
bad information in the icon structure. Reading the same icon with
a custom written C program just produces the read/write error requestor,
as expected; no crash.

I don't know if it matters, but the disk in question had a whole
directory full of icons, and several tracks were bad, trashing several
icons in the directory. My C program successfully examined all files
on the disk without producing anything more than the read/write
error requestor.
