Description Mac Michaels 2011-06-14 22:15:19 UTC 
Application: partitionmanager-bin (1.0.3)
KDE Platform Version: 4.6.3 (4.6.3) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-gentoo-r6 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:

I created an ext4 file system with a label "VAULT3" on the fourth partition of /dev/sdb and checked it. I realized after finishing that I should have created an extended partition first as I was not using all the remaining drive capacity. So I deleted the ext4 partition just created. Kconfig crashed immediately!

-- Backtrace:
Application: KDE Partition Manager (partitionmanager-bin), signal: Segmentation fault

Note: I did not click the apply button or close the application before the crash!

Restarted Kconfig: 
  Created extended partition to hold remainder of disk capacity.
  Created logical partition for ext4 file system.
  Clicked "apply" button (for the first time ever in all this).
  Everything worked properly after about 4 minutes to actually format the partition.

Mac, thanks for the bug report. I can reproduce the crash.

Please do note that there is no need to schedule a check operation for newly created file systems as KDE Partition Manager will always check a file system after creation. That's why this crash went by unnoticed for so long: It's not something you ever need to do ;-)

Note to self: Either merge the CheckOperation with the CreateFileSytemOperation (that might confuse users though) or with the DeleteOperation.
Comment 4 Volker Lanz 2011-08-28 13:59:43 UTC 
SVN commit 1249904 by vlanz:

Merge CheckOperations with NewOperations so when a new partition is deleted
before applying we don't get a dangling pointer in the CheckOperation.
