Description Mathieu Tarral 2011-11-23 20:48:11 UTC

Application: partitionmanager-bin (1.0.60)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.1-CHAKRA i686
Distribution: "Chakra Linux"

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

I created a LiveUSB using dd if = / of = / dev / sdX, and I wanted to format the same USB drive. so I recreated the partition table, the operation was successful, then I did format it FAT32 and PartitionManager crash

- Custom settings of the application:

I noticed that to create a liveusb with dd if = / of = / was that if we subsequently reconnects the same LiveUSB on a Linux computer, there are two devices that are recognized, the first being the key space and the second is a weird thing in UDF format (CD-ROM). I think it's waste of a copy of dd that are poorly managed after.

I have to go through Windows to format it correctly.

The crash can be reproduced every time.

Comment 1 Volker Lanz 2011-12-16 18:53:03 UTC

Thanks for the bug report.

If you can indeed reproduce the crash, please install debug symbols (the KDE crash manager should guide you through this) and post a meaningful backtrace.

Comment 2 Mathieu Tarral 2011-12-16 20:33:51 UTC

Thanks for interesting to this bug.

I'm sorry, but there is no partitonmanager-dbg package on Kubuntu.
Furthermore, I think I already have installed debuguage symbols with Dr. Konqi

Nevertheless,  I will try to reproduce the bug again and check for debuging symbols with the Dr. Konqi assistant.

Comment 3 admin 2012-02-13 05:30:16 UTC

I have experienced this crash, just as it is described in the title. I had a Live USB drive that was previously created with a DD command. I opened up the KDE partition manager and selected my USB drive /dev/sde. At this point the screen showed that partitionmanager it did not recognise the partition file system type. I went ahead and deleted the unrecognised partition and applied the queued operation. Everything went fine, and now I had unallocated space on /dev/sde. Proceeding, I created a new EXT4 partition to take up all of the unallocated space on the drive. As soon as I hit Apply, the computer crashes. I see a black screen (http://i.imgur.com/YMU0l.jpg) and I am unable to get back into KDE desktop. I had to take a snapshot with my camera and poweroff.
I am running LinuxMint 12 KDE(4.7.4)

Comment 4 Volker Lanz 2012-02-13 07:24:54 UTC

Thank you for your comment, admin.

What you're seeing is a kernel bug. The screenshot you took shows a kernel backtrace. This is not related to the issue Mathieu is seeing and is not a problem with KDE Partition Manager itself.

You should probably report this as a kernel bug to your distribution or to the Linux kernel mailing list.

Comment 5 Volker Lanz 2012-02-13 07:32:17 UTC

Mathieu:

Are you on Kubuntu or Chakra? You've specified you're using Chakra in your original report (and the backtrace shows their patched KDE Partition Manager library names), but are referring to Kubuntu now in your comment.

If there are no debug symbols for KDE Partition Manager on your distribution, please speak to them about that.

Also, you said you could reproduce this crash every time in your original report. Is this not the case?

Comment 6 Mathieu Tarral 2012-02-22 02:35:16 UTC

Today, I cannot reproduce the bug anymore. It seems to have been solved since I posted here.

Thanks to you.

Comment 7 Volker Lanz 2012-02-22 08:34:07 UTC

Setting the entry to fixed suggests code has been changed. Chaning resolution to invalid.
