quodlibet
very reproducible crash when playing results of a complex query with shuffle on
Steps to reproduce
- Have songs in a bunch of playlists being abused as something similar to tag (e.g. fast, slow, acoustic, electric, 80s, 90s, etc)
- Create a complex query to build a song list based on playlist-as-tag membership, lastplayed, rating, etc.
- Listen to the results of said query
- Enable shuffle
Expected Output
The song list should play normally.
Actual Output
Quod Libet will very reliably crash within a few songs.
Test System
Which version of Quod Libet?
4.6.0 Flatpak, and versions prior. This has actually decimated my ability to use QL for about 18 months, and I haven't had the mental bandwidth to follow up on making an issue.
Which operating system
Debian 12 (BunsenLabs remix, so Openbox desktop)
If it's audio-related, what back-end?
?
Additional Information
A segfault is reported before Quod Libet crashes, as in minutes before. I have no idea if it's relevant to the actual crash.
$ flatpak run io.github.quodlibet.QuodLibet

And then the program just quit.
Possible duplicate of #4373, except for me it doesn't always crash after exactly 2 plays.
I took particular note of this comment: https://github.com/quodlibet/quodlibet/issues/4373#issuecomment-1732379286
Because my complex query does indeed include a (lastplayed > ___) component.
Hi, I'm also affected by this bug, every two play, my quodlibet version is 4.6.0.
