Description ali.sherif10 2015-05-08 16:27:26 UTC
While I was transfering files, I tried to do something. Then Plasma crashed and screen became black forever. After restart then logging in, everything is black, ALT+F2 shows command at the top, but I can't open any program and if I click laptop power button, it's shutdown without prompt to logout, restart or shutdown. This always happen everytime I log in.
Deleting some folders in .config didn't work.
I created an account in recovery mode. After logging in, everything is slow and network manager was corrupted. I couldn't connect to wifi.
I reinstalled the distribution and Plasma crashed again. I had to reinstall it again.
It seems that Plasma 5 is vulnerable to corruption after crash.

Reproducible: Sometimes

Steps to Reproduce:
1. Transfer files
2. Do anything until plasma crashed.
Comment 1 ali.sherif10 2015-05-08 16:30:12 UTC
I use Kubuntu 15.04.
Comment 2 David Edmundson 2015-05-10 13:13:33 UTC
can you include the output of

ls -l .config
ls -l .cache
Comment 3 ali.sherif10 2015-05-10 13:54:45 UTC
After corruption, I had to reinstall the distribution, so I don't know if the output'll be useful.

Comment 4 ali.sherif10 2015-05-13 00:00:43 UTC
I provided output, but no one changed bug status. Do you want any information?
Comment 5 ali.sherif10 2015-05-23 18:46:36 UTC
Plasma crashed, after I did similar thing and it was reported by me in bug 342438. I suspect it happened again. Sorry, I couldn't put the report in this bug.
Look at the crash, I reported.

*** This bug has been marked as a duplicate of bug 342438 ***
Comment 6 ali.sherif10 2015-05-23 18:56:48 UTC
How did it happen?
Firstly, I ran sudo dolphin, then transfered large folders. After transfer, I closed dolphin.
Crash happen, after I opened dolphin normally, after what happened above.
Now, desktop is black except the default panel, which is completely white. After a short time, the default panel disappeared.
ALT+tab shows all programs except Chrome.
Dolphin shows images preview, but Gwenview says that it can't open image of type ...
I can open PDF with dolphin.

I hope KDE isn't corrupted. Isn't there any way to return it to normal without erasing account or reinstalling the ddistribution? All of my passwords will be lost again.

Comment 7 ali.sherif10 2015-05-23 21:25:01 UTC
Unfortunately, KDE became permanently corrupted. The same behavior in comment 1 happened and I had to reinstall Kubuntu 15.04.
Because the same behavior in comment 1 happened, after I had restarted in comment 6, you should pay attention to crash information.
I made it a duplicate of bug 342438, because DrKonqi said so and asked if I want to attack crash information to this bug. I don't know if it's the right thing.
Comment 8 ali.sherif10 2015-06-09 16:20:23 UTC
1. I ran: sudo dolphin.
2. I copied files from a partition to an another.
3. I opened Steam.
4. I clicked on application launcher.
5. Plasma crashed.
I had to reinstall Kubuntu 15.04 like the previous report.
Should I change the bug to critical?
Don't ignore this bug. You can loose all of your data with a crash. If you want more data, ask me.

Comment 10 ali.sherif10 2015-06-09 16:27:19 UTC
I don't know if this is right.
I added regression, because KDE 4 was more stable.
I added release_blocker, because this bug would make using KDE 5 a hell.
Comment 11 Kai Uwe Broulik 2015-06-09 16:30:57 UTC
Do not run GUI applications as root.
Comment 12 ali.sherif10 2015-06-09 16:36:57 UTC
I changed version to 5.2.2, because plasma-workspace package version is 5.2.2 in Kubuntu 15.04.

@Kai Uwe Broulik, I ran dolphin as root, because the data were in a new partition, which I can't write into as I'm. I remember the deadly crash happened, after closing root dolphin then interacting with the default panel in the last time.
Thanks very much for replying to the bug. I hope I can provide you with all data you need.
Comment 13 ali.sherif10 2015-06-09 16:42:42 UTC
But you may be right, because in all crash cases: I opened dolphin as root then copied files from a partition to an another.

Comment 15 ali.sherif10 2015-06-09 20:48:35 UTC
After restarting, KDE was corrupted (As described above), even though Plasma didn't crash (At least crash menu didn't appear). It seems root dolphin corrupts some KDE files.
I think I'll have to use copy command to copy from partition.
