control-panel segfaults upon invocation
Last modified: 2008-05-01 11:37:53 EDT
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: root@Young /root]# gdb /usr/bin/control-panel GNU gdb 4.18 Copyright bla bla. This GDB was configured as "i386-redhat-linux"...(no debugging symbols found)...

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?
[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 ftp://ftp.redhat.com/pub/rawhide/. Not all mirrors carry Raw Hide. The original press release that announced the creation of Raw Hide is viewable at "http://www.redhat.com/about/1998/press_aug1498.html".
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
Tim - is this fixed if you grab the latest control-panel build (3.14-1)?
Malformed .init file problems are fixed in 3.15, coming soon to a Raw Hide (ftp://ftp.redhat.com/pub/rawhide/i386/RedHat/RPMS/) snapshot near you.
