Crashes after screen wakeup on Ubuntu 19.10

[loxK]

I get this error:

Hi @loxK, thanks for the report. Have you tried with the master branch? Also is this on wayland, xorg or both?

[loxK]

I didn't try master and it is on xorg

[loxK]

More information. It works on boot but then crashes when waking up the screen. Restarting Gnome Shell doesn't help, uninstalling, reinstalling doesn't either.

This is maybe related ? ubuntu/gnome-shell-extension-appindicator#228

[jonian]

Try replacing in handlers.js file in registerHandler function:

// Replace this line
const key = `${object}[${name}]`

// With these
const uid = Math.random().toString(36).substr(2, 9)
const key = `${uid}-${name}`

Please report back if the issue is fixed.

Made the change, rebooted, locked the screen and the extension is still active on login in.
It seems fixed. Thks!

[loxK]

Damn it crashed again and I don't find any occurrence of 'unite' in the shell logs ..., But I was able to uninstall/reinstall and activate it again this time.

I have applied the fix but it still crashes sometimes:

It happens when the screen goes black, not on session lock/unlock

This may be related, or not ... You tell me https://bugzilla.gnome.org/show_bug.cgi?id=781760

Closing as I can't reproduce this issue. If it is still present please open a new issue with fresh logs.
