Version: 4.4.3 (using KDE 4.4.4) OS: Linux Recently, I've taken to checking System Monitor more often, and have noticed that, after a day use, the process named "kontact" is present in the list of running programs although I've just closed it. Nothing changes if I wait a couple of minutes, or until I shut down. If I right-click the process and choose "Show Application Window" nothing happens. If I click on Kontact in the main menu, cursor bounces for a while, there's some activity in the task bar, but ultimately it fails to start. So it's not like the app is really running, although it behaves as if trying to open another instance of the same application. I have to manually kill the process, if I want to restart Kontact. This is reproducible everyday, after hours and hours of use. After a whole day, it eats up to 150 MB of RAM, and may be problematic if the process just sits there uselessly and unnoticed. However, I've tried to start the programme, use it for shorter periods, then quit it, and the process exits properly. Reproducible: Sometimes OS: Linux (i686) release 2.6.32-22-generic Compiler: cc
I confirm, kontact does not close propely, process is still running. Qt: 4.6.3 KDE: 4.4.5 (KDE 4.4.5) Kontact: 4.4.5
I can confirm this too. KDE 4.5.3 using Kubuntu 10.10 PPA
still exists in 4.6 using Kubuntu PPA Backports Starting Kontact after quitting, didn't killed the process manually, you get an crash at startup with the following backtrace: Application: Kontact (kontact), signal: Segmentation fault [Current thread is 1 (Thread 0x7ffa8327e780 (LWP 21967))] Thread 3 (Thread 0x7ffa632e8700 (LWP 22051)): #0 0x00007ffa89b87203 in __poll (fds=<value optimized out>, nfds=<value optimized out>, timeout=-1) at ../sysdeps/unix/sysv/linux/poll.c:87 #1 0x00007ffa8b5fc240 in ??
