Describe the bug

I keep ksnip on an "application server" - where people log in remotely to run various programs (I store all AppImages there - makes updating much easier :) ). Ksnip normally runs without any issues, but, I recently discovered that when one user has ksnip open, it will not start for any other user.

To Reproduce

Have one user start ksnip. Any attempts by another user to run ksnip get nothing but the message "Critical: Unknown platform, using default X11 Image Grabber" (this message always appears on startup, but usually ksnip still starts after displaying it).

Expected behavior

I expect multiple users to have the ability to run ksnip simultaneously.

Desktop (please complete the following information):

• OS: Linux
• Distribution in case of Linux: none (built from source)
• Window System in case of Linux: X11
• ksnip version: tried both 1.10.1 and the "continuous" build
• How did you install ksnip: AppImage
