Description of problem:

Here's what I get when I invoke retrace-server-interact, which tells me the command to use.  It looks like we need double quotes around the crash command, i.e. "crash -i ... vmlinux"

$ retrace-server-interact 466914912 crash
If you want to execute the command manually, you can run
$ /usr/bin/mock --configdir /cores/retrace/tasks/466914912-kernel shell crash -i /cores/retrace/tasks/466914912/crashrc /cores/retrace/tasks/466914912/crash/vmcore /cores/retrace/repos/kernel/i386/usr/lib/debug/lib/modules/2.6.18-274.7.1.el5PAE/vmlinux

I try the command it tells me to invoke crash manually and get an error:
$ /usr/bin/mock
--configdir /cores/retrace/tasks/466914912-kernel shell crash
-i /cores/retrace/tasks/466914912/crashrc /cores/retrace/tasks/466914912/crash/vmcore /cores/retrace/repos/kernel/i386/usr/lib/debug/lib/modules/2.6.18-274.7.1.el5PAE/vmlinux
Usage: 
    usage:
           mock [options]
{--init|--clean|--scrub=[all,chroot,cache,root-cache,c-cache,yum-cache]}
           mock [options] [--rebuild] /path/to/srpm(s)
           mock [options] --buildsrpm {--spec /path/to/spec
--sources /path/to/src|--scm-enable [--scm-option key=value]}
           mock [options] {--shell|--chroot} <cmd>
           mock [options] --installdeps {SRPM|RPM}
           mock [options] --install PACKAGE
           mock [options] --copyin path [..path] destination
           mock [options] --copyout path [..path] destination
           mock [options] --scm-enable [--scm-option key=value]


mock: error: no such option: -i

But I think all we need to do is enclose the crash command with double quotes:

[dwysocha@optimus misc]$ /usr/bin/mock --configdir /cores/retrace/tasks/466914912-kernel shell "crash -i /cores/retrace/tasks/466914912/crashrc /cores/retrace/tasks/466914912/crash/vmcore /cores/retrace/repos/kernel/i386/usr/lib/debug/lib/modules/2.6.18-274.7.1.el5PAE/vmlinux"

Version-Release number of selected component (if applicable):
retrace-server-1.10-1.el6.noarch


How reproducible:
Every time.


Steps to Reproduce:
1.  Queue a 32-bit vmcore.  Run "retrace-server-interact <taskid> crash" and observe the 'manual command' given to run crash.
2.  Exit the intitial crash session.
3.  Try to invoke crash with the command given by 'retrace-server-interact'


Additional info:
This should be easy to fix (only gotcha might be some quoting, not sure) but is low priority.
