Description Eric S 2017-05-29 01:14:11 UTC

Application: partitionmanager (3.0.0)

Qt Version: 5.8.0
Frameworks Version: 5.33.0
Operating System: Linux 4.8.6-1-CHAKRA x86_64
Distribution: "Chakra"

-- Information about the crash:
- What I was doing when the application crashed:
I unmounted a partition on removable media (SD drive)
then deleted a partition
then added a new partion
then I ejected  the media (having forgotten to "Apply")
I reinserted the media, and hit apply. 
Clearly this was wrong, but partition manager should not crash.

-- Backtrace:
Application: KDE Partition Manager (partitionmanager), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".

Strange, I can't reproduce it (I have USB stick). Even though as you say it looks wrong to do these steps they worked. Applying after reinserting my USB I clicked Apply and it created new partitions.

Can you try with some other media and see if it is always reproducible in your case?

Comment 2 Andrius Štikonas 2017-12-15 17:02:14 UTC

I can't reproduce this, so I'll close. And it should definitely not crash when libparted backend will be replaced with sfdisk backend.
