Comment 21 for bug 909195

I've still have this issue in 0.94.3 on Manjaro (and also before on Ubuntu). Running shutter from cli throws some light into the issue:

```

```

The problem with this is that even if I could find and install the missing packages to make these plugins work, there's no user-friendly way to tell that something is failing (besides the "updating plugins" message, that looks more like a bug than a local error). I don't even use the upload feature, so removing `/usr/share/shutter/resources/system/upload_plugins/upload/*.pm` fixes the issue for me.

In any case, I'd expect `--min_at_startup` to skip showing the "updating plugins" message, so that's still a bug.
