Hi all!
There are
Kubuntu 10.04
KTorrent 3.3.4

Problem:
I start KTorrent, it's window does not displayed. System monitor detects 85-95% CPU usage by process ktorrent.
I did nothing incorrect with OS or KTorrent's settings. Yesterday it works.If it runs in terminal:
Warning: Connecting to deprecated signal QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString)
Warning: Calling appendChild() on a null node does nothing.
Warning: Calling appendChild() on a null node does nothing.
Warning: Calling appendChild() on a null node does nothing.

Question:
What can I do to fix this problem.

Problem was solved by deleting ~/.kde4/share/apps/ktorrent

Thank you in advance
