Comment 2 Otto Bruggeman 2005-05-25 21:11:14 UTC 
Hi Bill,

I cant reproduce atm, I dont have a working linux installation on my workstation and my linux laptop is still in the Netherlands. It looks from the crash that there is again a problem in the navigation part. All the more reason to get rid of it. I dont know when I will have time to fix this for good but maybe for KDE 4.0. I also dont know if I can backport a fix for it since the changes will be massive when I am done but we will see what happens and how much time I have.

Cheers,
Otto

> All the more reason to get rid of it.

It's already gone in kompare3_branch ;-)
Comment 4 Jeff Snyder 2005-06-06 21:44:12 UTC 
This is gonna be a little spammy... I'm reassigning everything that's currently 
assigned to bruggie (who's been the default assignee for bugs since time began) 
to the new list address. 
 
Bruggie: if you're working on one or more of these atm, please snatch 'em 
back.. 
 
Everyone, esp. Joshua and Bruggie: if this genrates 33 mails, my sincere 
apologies..
Comment 5 Otto Bruggeman 2009-03-11 22:38:17 UTC 
Should be fixed in 4.2.1 and higher.
