Description maavl 1999-11-24 13:08:36 UTC
After upgrading from 5.1 to 6.1, any attempt to start control-panel results
in a segfault. Here is some gdb and rpm output:

There was severe sloppiness in older vesions of control-panel.  Can you try the
latest version (3.13 or later) from Raw Hide and let me know if you continue to
experience crashes?

Comment 2 Nalin Dahyabhai 2000-03-10 16:18:59 UTC
[per private email re: what is Raw Hide?]
Raw Hide, our release containing the latest versions of packages from our devel
tree, is available at  Not all mirrors carry
Raw Hide.  The original press release that announced the creation of Raw Hide is
viewable at "".

Comment 3 Tim Waugh 2000-03-31 10:40:59 UTC
I don't think this is fixed in 6.2.  Here's how I can reproduce it easily:

# cd /usr/lib/rhs/control-panel
# touch comanche.init
# control-panel

A possible work-around is:

# cd /usr/lib/rhs/control-panel
# mv comanche.init comanche.init.notused

Comment 4 Bill Nottingham 2000-03-31 19:46:59 UTC
Tim - is this fixed if you grab the latest control-panel build (3.14-1)?

Comment 5 Nalin Dahyabhai 2000-03-31 22:16:59 UTC
Malformed .init file problems are fixed in 3.15, coming soon to a Raw Hide
( snapshot near you.
