Waybar: Segmentation fault when clicking on sway workspace

[ainola]

I'm finding that clicking on any of my sway outputs will eventually crash Waybar as of 0.6. It's often not an immediate thing; The bar will crash after some light use. This is on Arch Linux.

Happens to me too

A bisect suggests that cccf60c30ec093362bc2c825dc8ccb9316d6bb32 is the commit that introduced this issue.

Happens to me too, I think it happens when title text switches too quickly (like switching browser tabs quickly, or switching workspaces quickly).

[Alexays]

Can anyone give me a bt with debug symbols? :)

[Alexays]

Fixed with d027243a19997b24a26ae962e28ccdbe434a1153

[betseg]

Still happens to me on 0.6.1 (on Arch).

[Alexays]

Anyone able to give me a way to reproduce the problem that works every time?

[Alexays]

Does 5a44c8c6debcf92722f6920b81ed44db8736a5da fix the issue?

[ainola]

I haven't had an issue since the upgrade so I cannot test, unfortunately.

Yes, it does fix the issue for me.

Does 5a44c8c fix the issue?
