[Linux] Crash due to "Timeout when taking screenshot"

[MariusAlbrecht]

What happened?

honestly dunno for the exception. This:

12:07:27 - ERROR   - normcap.screengrab.dbus_portal:88 - No response from xdg-portal within 7s!
12:07:27 - WARNING - normcap.screengrab.dbus_portal:199 - Timeout when taking screenshot!
12:07:27 - WARNING - normcap.screengrab.dbus_portal:204 - Didn't receive screenshot! Are permissions missing or did you cancel the intermediate dialog?

appears after opening the "options"

How did you install NormCap?

Python Package (pip install)

Operating System + Version?

Ubuntu 23.04

[Linux only] Display Server (DS) + Desktop environment (DE)?

Wayland, Gnome

Debug log output?*

[dynobo]

Hi @MariusAlbrecht, thanks for reporting this problem!

It looks very similar to what was reported in https://github.com/dynobo/normcap/issues/555 . Would you agree? Shall we close this issue here as duplicate, and continue in that earlier issue?

[MariusAlbrecht]

I honestly did only 'follow orders' and didn't check for duplicates like I normally would when opening an issue. In hindsight that wasn't very reasonable I'll take a look and edit this response in probably about 15min

edit: could very well be the same issue! at least the latter part I wanna empathise the first few lines again where an error appears after only opening the options (and especially not actively trying to take a screenshot). I cannot judge whether that could be the same issue concerning screenshots (seems like it but I don't know the app internals)

[dynobo]

Hi @MariusAlbrecht , could you please check if this problem persists with the latest release? (At least the potential duplicate #555 got solved with the latest update...)

[MariusAlbrecht]

will try that in the next few days ✨

Did some testing and all seems to work well now. Installed via flatpak tho
