Package: konqueror
Version: 4:3.5.5a.dfsg.1-5
Severity: serious

On amd64, Konqueror frequently fails to launch or occasionally freezes
up completely while it's already running. In either case, it's becase
konqueror is blocking forever trying to read file descriptor 8.

Killing kded and gam_server and restarting any KDE apps lets konqueror
load again. I have never seen this bug occur on x86.

I'm unable to get a useful backtrace from kded or gam_server.

OK. It went away when I moved the .kde directory out of the way, so I'm 
closing the bug. I'm hoping that by removing a couple of 
problematic-looking files from the version that I keep in Subversion 
and by checking out a fresh copy, I have eliminated whatever cruft was 
breaking konqueror/kded/gam_server without having to reconfigure 
everything from scratch. But ultimately, that's my problem not yours.
