Version: unknown (using 4.00.81 (KDE 4.0.81 >= 20080527), compiled sources) Compiler: gcc OS: Linux (i686) release 2.6.24-16-generic If I remove the feeds tab from the lateral sidebar (through Settings->Configure Kontact, unchecking the 'Feeds' checkbox), and click on Ok or Apply, kontact crashes. Backtrace: http://pastebin.com/f292a1b19 The tab works perfectly fine, it's just removing it that causes the problem. I haven't tried to remove other tabs.
Confirmed with 2 different backtraces depending on the testcase : Test 1 : -Run kontact but don't start the embedded akregator - Uncheck the box => you get the bt linked above. Test 2 : - Run kontact, click on the feed icon - Uncheck the box => Application: Kontact (kontact), signal SIGSEGV [Thread debugging using libthread_db enabled] [New Thread 0xb4ff6940 (LWP 24286)]

SVN commit 818811 by ereslibre: Add some useful checks on the model. The most important thing here is that Kontact now doesn't crash when a module is unloaded, even if it is the current one which is loaded. The most important change in here is the deleteLater(), which will delete the plugin after the model has been updated and the model won't try to access to an invalid pointer.
