Application: partitionmanager (3.2.1) Qt Version: 5.9.4 Frameworks Version: 5.44.0 Operating System: Linux 4.15.16-300.fc27.x86_64 x86_64 Distribution (Platform): Fedora RPMs -- Information about the crash: - What I was doing when the application crashed: I resized a partition and the operation succeeded. I was viewing the detailed command line report in the window and scrolling through it when Partition Manager crashed. No attempt to reproduce it because I don't need any other partitioning operations. - Unusual behavior I noticed: This is done from a Fedora 27 KDE live media (respin 2018-04-15). The PC has an NVIDIA GPU and is currently using the nouveau driver which causes random and fairly minor graphical artifacts in all applications (especially text boxes and buttons) but this hasn't impacted the stability of any other applications, so is unlikely to be related to the crash. -- Backtrace: Application: KDE Partition Manager (partitionmanager), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

Maybe there is any more information that you can provide? At least what was the type of file system and maybe the rough size before and after? So from what I understood, you clicked "Details >>" button and was just scrolling down? It's even stranger that crash happened during scrolling... KPM is not doing anything in particular while you scroll... So far I can't reproduce it and if I can't reproduce then there is no way I can fix it. Somehow backtraces in kpmcore often blame Partition::sectorsUsed even when the problem is elsewhere, so unfortunatly backtrace won't be enough...
It was a GPT disk and I was resizing a Windows NTFS partition (primary type but a data partition, not Windows system, flags: msft-data). It was positioned last on the disk and I shrunk it from 490 to 440 GB, to free up space at the end of the disk. As the operation first started, I clicked opened the collapsible item in the top part first and then clicked "Details >>". I scrolled a few times at the start of the operation. Then I didn't touch it and let it finish. I came back after it had finished, saw "successfully completed" and scrolled to the top to review the output and as I was scrolling/looking at it, it crashed. I can't say with certainty whether it's related to scrolling or if it happened exactly when scrolling, because that's not something I paid attention to. I think that's all the detail I can provide. I can try to play around more with it when I have the time and see if I can reproduce it. But I don't know how effective it will be because I can't really do resizes of this magnitude (and under the same circumstances unless I reformat it with Windows) and this is my production system. I hope these details can help you and I'm willing to do what I can to help narrow it down if possible.

(In reply to Andrius Štikonas from comment #4) > *** Bug 415929 has been marked as a duplicate of this bug. *** It's very likely to be fixed in kpmcore git master. If it still doesn't work in future releases (I guess 4.2.0) please reopen.
