Description Christoph Bartoschek 2006-12-17 20:25:21 UTC

Version:            (using KDE KDE 3.5.5)
Installed from:    SuSE RPMs

I am using my program from http://www.pontohonk.de/kde/ssh.html (I'll also attach it) to add keys during startup to ssh-agent. This works most of the time but sometimes it hangs in the call to KWallet::Wallet::openWallet(localwallet); The messages in .xsession-errors are:

startkde: Starting up...
kbuildsycoca running...
akode: Guessed format: xiph
Starting askpass

I do not know which lines are related to the problem and which not. There seems to be an error in DCOP communication. Strace on the programm shows that it is waiting for data:

Do you still see this problem with a recent version of kwalletd (either 3.5.9+ or 4.x)?

Comment 3 Christoph Bartoschek 2008-10-29 08:59:54 UTC

Yes I do with KDE 3.5.9+

Comment 4 Michael Leupold 2008-10-29 09:17:09 UTC

Damn. I hoped this had just gone away :) Unfortunately KWallet is no longer under development for the KDE3 platform. As I started developing for KDE with KDE4 I don't know much about DCOP. As you stated it does however seem like there's an error in the DCOP service.

Comment 5 Christoph Bartoschek 2009-04-21 00:04:19 UTC

I a test with kde 4 i could not reproduce this.

Comment 6 Michael Leupold 2009-04-21 00:05:58 UTC

Thanks a lot. Now it's finally time to close this bug :-)
