KCrash

[squeevee]

Some kind of crash handler is desired, if for no other reason than because a dialog saying that the application crashed is strictly better than the UI spontaneously disappearing with zero explanation, and (at least on Linux, but possibly on Windows too?), the application must go out of its way to make that happen.

My first choice of crash handling library is Google Breakpad (see #8) but for various reasons that's looking difficult. Integrating it is going to be a project

KCrash doesn't have the same features as Breakpad, nor does it support as many platforms. However:

• It seems quite capable of launching an "Addle has crashed" dialog.
• It easily works with Qt and CMake
• It supports Linux and Windows

Which makes it perfectly adequate for the time being.

KCrash is licensed LGPL, but it's tightly paired to DrKonqi which is licensed GPL2, and I'm not sure if it's supported on Windows. It may be more illuminating to work on this this after making a stable Windows build of Addle.
