Description Richard Lärkäng 2005-02-07 20:41:33 UTC 
Version:            (using KDE Devel)
Installed from:    Compiled sources
OS:                Linux

When I try to read a newsgroup from a server which requires authentication, and supply a username but an empty password knode stops at 6% and nothing happens. Almost all the time it will freeze too but not always. But those times when it doesn't freeze, it is still impossible to cancel the request.

I removed the comments on some of the debug-output, and here's the relevent part (I hope):
knode: KNNetAccess::startJobNntp(): job started
knode: KNFolderManager::setCurrentFolder() : folder changed
knode: KNProtocolClient::openConnection(): opening connection
knode: KNProtocolClient::closeConnection(): closing connection
knode: KNNetAccess::threadDoneNntp(): job done
knode: KNNetAccess::threadDoneNntp(): authentication error
knode: KNNetAccess::threadDoneNntp(): trying again with authentication data
knode: KNProtocolClient::openConnection(): opening connection
knode: user: larkang
knode: Password required
Very strange! got a DCOPReply opcode, but we were not waiting for a reply!

This is with kdepim from yesterday, but I've seen this for a while.

Prevent wallet operations from the network thread, this causes the thread to hang.
