I've just started by freshly built KDEPIM trunk on the desktop, and I got a crash in one of the Nepomuk service stubs... but that's not the reason for my amazement :)
No, the reason is that instead of the way-too-common and ugly Windows crash dialog, I got this nice KDE Crash Handler that surely looks familiar to the Linux users :
Even nicer, the "Developer Information" tab gives a complete stack trace at the time of the crash, giving us precious information to track it down :
This will not only help us during testing, but it will also make it easier for the casual users to report issues and provide the necessary information to fix those unfortunate mishaps.
That's a nice little feature, and it was implemented by Ilie Halip, as part of a GSOC project. Nice work Ilie !
