Version: 1.11.0 (using KDE 4.2.0) OS: Linux Installed from: Ubuntu Packages Kmail crashes every time it starts if there is no internet connection available. It can be reproduced by just disabling wireless connection on my laptop and starting kmail. It crashes every time. When enabling internet connectivity and start kmail everything goes fine. This happens ONLY if Check mail on startup is checked in Accounts settings. If not, and there is no connection, kmail starts regulary and when check mail is clicked kmail just said Unknown host pop3.xxx.xxx Here is backtrace...

Reassigning to Akonadi.
SVN commit 923208 by krake: Using nested event loops to achieve synchronous call behavior while doing Akonadi jobs has created way to many issues due to unexpected re-entrancy. This is basically backport of a series of changes in trunk which replace this form of blocking with real blocking of the caller and delegating the Akonadi job execution to a worker thread. This should fix all the bugs this is sent to. If they remain with 4.2.1 once it is released, please re-open. Darío, in case I missed some of the eventloop related bugs, please feel free to close them as well.
