How does the code know the size to allocate? Version-Release number of selected component (if applicable): 3.0.6 FC24 64bit
Warnings aren't bugs!, if you think otherwise report it upstream. https://github.com/linuxmint/nemo/issues
This actually is a harmless (?) old bug in GTK itself. See bug 1488249 for further details. *** This bug has been marked as a duplicate of bug 1488249 ***
