same to me. KDE Partition Manager 1.0.60
To avoid segfault I placed some task(for exsample check some ext3 partititon) before resize/move operation.

Still happening for me in Fedora 22 with KDE5.
Comment 6 Andrius Štikonas 2015-09-16 15:23:12 UTC 
I still can't reproduce it. Can you write what steps are required to reproduce it. I just tried to move ext4 partition earlier in the disk and it worked.

Check if fileSystem pointer is nullptr before trying to read used space

Hopefully it fixes this crash.
