f14 x86_64 konqueror 'the process for the file protocol died unexpectedly'

[John Pilkington]

Yesterday, after a week away, I updated this system.  It had been 
up-to-date before I went away. New kernel, and I thought some kde stuff. 
Since then several attempts to refresh konq file-management tabs have 
given a blank window, sometimes with this message in the border. 
Everything works as usual after a konq restart, until this happens again.

Two of the tabs were showing large folders, 100 GB (ext3) and 500 GB 
(ext4), both nearly full with video files.  I've since deleted quite a 
few to provide more headroom.  Anyone else affected?  I've never seen it 
before.
