[Interest] ideas how to debug this crash?

[René J.V. Bertin]

Hi,

Here's a backtrace I'm seeing under certain conditions in an application (a KF5 application built on/for OS X, kdebugdialog5):

Thread 0 Crashed:: Dispatch queue: com.apple.main-thread

Any ideas how to figure out the culprit?

NB: this involves a QPlatformPlugin which accesses the DBus, but a priori the same accesses are made in applications that never crash.

If possible I'd like to avoid using valgrind, because that's been a great tool mostly to cause KPs :-/

Thanks!
