when trying to start kmail over ssh with X forwarding, the first try is always unsucessful - almost immediately I get the following error (in less than 5 seconds - hardly any timeout due to network lag, sometimes it takes more to start kmail locally ...)

[kavol@kavol ~]$ kmail
kdeinit4: preparing to launch /usr/lib/libkdeinit4_klauncher.so
kdeinit4: preparing to launch /usr/lib/libkdeinit4_kded4.so
kdeinit4: preparing to launch /usr/lib/libkdeinit4_kbuildsycoca4.so

<unknown program name>(1593)/: Communication problem with  "kmail" , it probably crashed. 
Error message was:  "org.freedesktop.DBus.Error.NoReply" : " "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken." " 


on any subsequent try, I get these messages and kmail starts normally:

[kavol@kavol ~]$ kmail
kdeinit4: preparing to launch /usr/bin/knotify4
[kavol@kavol ~]$ kdeinit4: preparing to launch /usr/bin/kwalletmanager

while I suspect this problem probably is not specific to kmail, I didn't manage to reproduce with anything else
