Comment 2 Lubos Lunak 2008-07-21 16:23:17 UTC
SVN commit 835987 by lunakl:

Remove emitting of aboutToQuit() from KApplication::xioErrhandler() - the application
is not about to quit, it is about to fall flat on its face. There is really not that
much to do once KDE apps lose their connection to the X server. How that can happen
while the X server still continues to run is a different question and I don't know
the answer. It is quite possible it is caused by careless usage of one X connection
from several threads concurrently without proper locking.

Comment 3 Dr. Christoph Pospiech 2012-01-08 14:38:50 UTC
Where are we with respect to this bug report ? I (=original reporter) have moved on to Kubuntu Oneiric (linux kernel 3.0.0, KDE 4.7). Did kitchensync make it to KDE 4 ? If not, we might want to close this bug.
Comment 4 quentin.denis 2012-01-19 12:45:02 UTC
I am sorry to tell you that I had to give up developing kitchensync. I took it over from Tobias Koenig to make it work again with the new opensync API, but now that I have started my professionnal life I don't find any time to maintain kitchensync anymore. So let's close the bug.

Btw, kitchensync has been ported to KDE4 and basically works. The problem is more on the opensync side...
Comment 5 Dr. Christoph Pospiech 2012-01-19 13:40:05 UTC
OK, given the last comment (#4) I changed the status of the bug to "resolved" as "unmaintained". I hope that is OK.
