Screenshots

Contents in the bottom right will crash QS if I click it.

Additional info

No response

[pjrobertson]

The crash log points to the iTunes plugin. If you disable it, does that fix the problem?

[n8henrie]

Yes, that seems to do it.

I can't reproduce the crash in an Xcode build though. I don't see any iTunes related proxy objects in Contents; I do see a few errors about the plugin unable to be loaded, and others about unsupported architecture. Weird.

2022-05-04 10:40:40.745568-0600 Quicksilver[11044:59603] Moving unsupported plugin 'iTunes Plugin' to PlugIns (disabled). Quicksilver only supports 64-bit plugins. i386 and PPC plugins are being disabled to avoid repeated warnings.

AFAIK the iTunes plugin isn't working anyway, so I'll just disable. It would be fun to make a new plugin for Music.app, perhaps I'll chip away at that.

[pjrobertson]

Quicksilver only supports 64-bit plugins. i386 and PPC plugins are being disabled to avoid repeated warnings

That warning message probably needs updating. If you do a global search in Xcode for "i386 and PPC plugins are being disabled" you'll probably find where the message is, and can improve it to something more meaningful.
