Bug: Tab-opening actions crash Grayjay Desktop

[Onihikage]

Reproduction steps

• Scenario 1: middle-click a URL, such as in a YouTube video's description
• Scenario 2: press ctrl-t from anywhere in the app

Actual result

In both scenarios, Grayjay freezes for about a second after the input, then crashes.

Expected result

• middle-clicking a URL should either open the URL in the default browser or do nothing
• pressing ctrl-t should have done nothing since Grayjay doesn't have a tabbed interface

Can confirm the ctrl-t bug is present on the flatpak build of the app. @Zvonimir-FUTO Does this happen on the regular builds too?

[Zvonimir-FUTO]

@MoralCode it appears to be only a flatpak issue.

[MoralCode]

@Zvonimir-FUTO what behavior do you observe when Ctrl-T is pressed on non-flatpak installs? does a new tab/window open successsfully? or is the application blocking that shortcut and doing nothing?

App just crashes, original windows closes and below are debug logs.

So this is not an issue unique to flatpak?

[Zvonimir-FUTO]

Only crashes for flatpak.
