fix for yet another occurrence

Patch for yet another occurrence of this error found by David Binderman:

https://bugzilla.novell.com/show_bug.cgi?id=443369

Raising priority to high. This typo-like bug breaks other packages two years for nothing. It's easy to apply two one-line patches like these.

This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

More information and reason for this action is here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

proposing as F12Target

And it would be nice to have this CoolKey fixes in time for the upcoming NSS test day.

Sounds like a good idea.

At least bug 245678, bug 246052, bug 250738, bug 356971 and bug 497758 also contain patches. It would be nice to apply all of them and make new bugfix release.

Bob:

I tried out the patches for this bug. They seem to work fine.

r+ for this patch...

There is one other place that is still missing...
~PKCS11Object in object.h. both the 'delete label' and 'delete name' should be
delete [] label; and delete [] name;

This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '11'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 11's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 11 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.

Both issues are already fixed:
