I have the same problem. I can sometimes logout (not shutdown) from KDE without problems. If I try to shutdown, kwalletmanager crashs. If he not crashs, he wait ("ps aux" says as last process: "sleep 5"). So: this "waiting" can make it possible, that system goes down, but X (kdm) is still active. The message "will now halt shutdown /dev/hda" ist usual 1 second before "power off" - by me there is no "power off".
I see no kwallet icon (only in status bar of konqueror in webbroser mode). If I click there I see only gray window (no wallets, no white container). And this window crashs. If I open kwalletmanager after this, I see the wallets in kwalletmanager window and the icon i the try... (very strange) I try now to logout without restoring session (for me: not realy a solution) -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
