Description Christoph Roick 2018-06-18 21:08:50 UTC

Whenever QtWebEngine is used, the signal handler assignments made by KCrash are overwritten by some internal crash handler inside the Chromium part of QtWebEngine. It results in crashes with backtraces put to stdout, instead of DrKonqi popping up.

This can be tested (supposing QtWebEngine is actually used) by reproducing BUG 394849 (using the PHP documentation in KDevelop and then closing the session).

I'm not sure how to handle this, just wanted to bring it up, because it might reduce the number of bug reports with applications just quitting without notification.

There seems to be a solution to the problem. Here is how it could work:
