Created attachment 262957 [details, diff]
ksplash libpng 1.5 fix from git master

untested and not yet backported to 4.6, but since there were not much changes in ksplash, i guess it will work

The patch doesn't fix the problem.

Both 4.6.1 and 4.6.2 have the fix.
Since 4.6.0 is not stable candidate and is overshadowed as-is closing as fixed.
