I downloaded the appimage from the website and ran it on Fedora 23 with MATE on a Lenovo X201 2-in-1 (executing it from the terminal after typing "chmod +x [name]"). When I tried to create a new file, the standard new file creation box came up, but when I hit "Create", it displayed two nested boxes, threw a segfault, and died. At the same time, my SELinux install said that "SELinux is preventing abrt-hook-ccpp from getattr access on the chr_file /dev/dri/renderD128." 

Traceback 

Reproducible: Always

Steps to Reproduce:
1. Download appimage from website onto a Fedora 23 install with SELinux and save to Downloads folder.
2. Make the appimage executable and start to execute it.
3. Hit Ctrl-N or open a new file from the menu.
4. When the dialog box shows up, hit the Create button on the bottom right.

Actual Results:  
Two nested blank dialog boxes show up, then the whole program disappears and the terminal reports a segfault. SELinux then states that "SELinux is preventing abrt-hook-ccpp from getattr access on the chr_file /dev/dri/renderD128" or something to that effect.

Expected Results:  
Krita creates a new file with no trouble and let me start editing it.
