Description Juergen Sauer 2005-07-26 11:21:59 UTC 
Version:           1.8.1 (using KDE 3.4.1, Kubuntu Package 4:3.4.1-0ubuntu0hoary1 ())
Compiler:          gcc version 3.3.5 (Debian 1:3.3.5-8ubuntu2)
OS:                Linux (i686) release 2.6.11.7

If kmail is used on a LAN using NFS mounted $HOME, it's possible that kmail left open and the user changed the workstation to another.
kmail reports correctliy that -if started again from other workstation- that it is running on the old workstation.
If kmail is killed by SIGINT (killall kmail i.e.) to close kmail on the old workstation where it was left behind and forgotten, it does not remove the lock/hint/pid file.

If kmail is now started on the other workstation again, it shows up a now wrong hint dialog, that it is still running on the old station. Clicking the dialog away solves all, but it is anoying to rookie users.

Simply removing the lock file in the sigint kill handling routine would solve it.

Why do you reassign a Bug as Wish ?
That's an _very_ anoying Bug in the practical use and insures unexpierienced 
users quite a lot.

Our support has many requests due this Bug.

Comment 3 Bernhard E. Reiter 2005-08-26 15:31:02 UTC 
I can confirm the bug with Kmail 1.7 proko2 branch after 2.0.1.
It is a real bug for coporate users.

Created attachment 12414 [details]
Patch for kmstartup.cpp.

I have the same kind of problem within KDE 3.4.0 (Kontact 1.1).
We have created a Patch for KMails kmstartup.cpp.
It fixes the problem for us. (Sets -1 as Pid value in the lock-file. Even if
Kontact gets SIGTERM or SIGHUP etc.)

Comment 7 Björn Ruberg 2009-12-21 20:19:35 UTC 
Haven't seen this problem for some time either. Considering fixed as long no one states the opposite.
