SUMMARY
***
I'm running Manjaro testing, so packages are close to version in Arch. Since the update few days ago, appimages stopped working. The ones I used were not starting because of "memory violation". I download a fresh, newest appimage and it won't even start because of kioslave5 crash. I checked other appimages, the same problem. In additional infomation below I'm posting crash info with debug symbols:
***


STEPS TO REPRODUCE
1. Download any appimage
2. Try running appimage
3. 

OBSERVED RESULT
kioslave5 immediate crash, appimage is not launching.

EXPECTED RESULT

Appimage launches correctly.
