I'm not sure if my problems are related but I've been having a lot of latency issues triggering quicksilver since my Sierra upgrade, sometimes a few seconds before it will come up. This morning I noticed quicksilver up there with Chrome in my battery usage too.

[joelbrock]

Maybe related as well: i'm having similar lagginess / crashiness but on El Capitan 10.11.8, with QS 1.4.2 (401A).

Symptoms: On startup i can trigger QS once. On subsequent trigger QS no longer responds. Maybe 2 to 3 minutes later the pane pops up. At other times the pane never pops up and i can see in Activity Monitor that QS is Not Responding and must be force quit. So essentially unusable.

I can't say for sure WHEN this began, it's been a while though. Perhaps since upping to OS X 10.11.

Not too much in Console.app to indicate what's happening:

12/13/16 9:37:16.091 AM Quicksilver[14604]: Unknown error calling sqlite3_step (11: database disk image is malformed) rs
12/13/16 10:03:40.272 AM Quicksilver[14604]: assertion failed: 15G1108: libxpc.dylib + 78286 [54D1328E-054E-3DAA-89E2-375722F9D18F]: 0x87

The gist indicates that there’s something related to disk mounting going on. Do you have any Event Triggers for “Disk Mounted” or “Disk Ejected”? Is QS indexing anything on an external drive?

[tiennou]

This is a weird gist actually. The Binary Image section makes me think we're not even fully started, but maybe that's a red herring... Also, would be nice to know what B49A61DD-1113-3ED1-A23C-B9FADC304D9A refers to, in case that's not our code...

[skurfer]

This is for 1.4.2:

% dwarfdump --uuid Quicksilver.app/Contents/MacOS/Quicksilver
UUID: 8E3D64D5-EA74-306B-8DD7-ECEBC6E10DFE (x86_64) Quicksilver.app/Contents/MacOS/Quicksilver

Each plug-in has its own binary of course, but none of them are loaded. That is weird.

[tiennou]

find ~/Library/Application\ Support/Quicksilver/PlugIns -type f -perm +111 -print -exec dwarfdump --uuid {} 2&>1 \; | grep B49A61DD-1113-3ED1-A23C-B9FADC304D9A ?

This gives me no results here (caveat, I'm still on 10.11). Maybe try against /Applications ?

[skurfer]

Give this test build a try and let me know if it’s any better. The version should show as “1.5.2:mine”.

@danielcompton - we haven't heard back from you in a while, so we're going to close this. Hopefully the latest build fixed this for you!
