Description Edward Donovan 2017-03-11 05:26:40 UTC

Application: partitionmanager (2.2.1)

Qt Version: 5.7.1
Frameworks Version: 5.31.0
Operating System: Linux 4.9.13-200.fc25.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

I have created new filesystems on a few disks, using Partition Manager today.  After the FS was successfully created, I hit the button to save the output.  Once, this has succeeded.  The next two times, after restarting and creating more fiilesystems on different disks, the application crashed immediately after hitting the button to save.  There was no prompting for a filename, and nothign was saved.

I'm not sure if this relates: the FSes I created were all on identical 500G hard drives.  Some were Ext4 and some XFS.  Crashes happened after one of each of those.  What might have been unusual was that the first runs of FS creation took several minutes.  Later runs took only several seconds.  This sounds like some kind of caching speeding process, but the work was done on new blank disks each time, so I'm not sure how.  I probably don't have all the possibilities in mind.  But I believe it was after the near-instant FS creation runs, that K.P.M crashed when I asked to save the log.  

Thank you.  :)

The crash can be reproduced sometimes.

This was fixed some time ago. It shouldn't crash on Fedora 26.

Pardon the duplicate, then.  I used the KDE bug reporting tool, and searched for dupes there, repeatedly, but maybe that doesn't work well enough.  Thanks.
