Migrating from the other issue:

Installed Keyboard Maestro last night, have the process plugin enabled and background processed cataloged, no QS crashes yet.

I'm still a novice at looking through these crash logs. If @skurfer or @pjrobertson have time to chime in about my interpretation below I'd appreciate it!

Highlights:

Exception Type: EXC_BAD_ACCESS (SIGSEGV)

Maybe a race condition somewhere here? Though I assume EXC_BAD_ACCESS is a use-after-free issue?

It looks like there are more reports of the stream deck being possibly problematic on the listserve.

I installed Keyboard Maestro and let it run for about a week with no apparent changes to QS stability or function. Could be that I need to install some plugins or configure it to provoke the behavior, but at least the default installation doesn't seem to interfere.

I had added both Keyboard Maestro and Streamdeck.app to my system before Qs became erratic (delayed key appearance and crashes). I decided to see if I could determine which (if either) could be causing the problem and I am finding that KM alone is not causing any problems I the past 24 hours. I will turn off KM and try SD next and see if the problems reappear.

I installed StreamDeck for a few weeks and was unable to reproduce any crashes in Quicksilver.

@ifuchs with the latest release are you still having this issue? If so, did you come up with any additional info regarding KM vs SD?
