Comment 1 Martin Flöser 2013-05-27 16:49:15 UTC 
uh the back trace is a new one. Exciting. Somehow I think it's related to the 
copy operation. Did you notice a general slowdown of the complete UI?

> The crash can be reproduced every time.
Are you sure about that? Sounds like it was a one time crash.
Comment 2 Thomas Lübking 2013-05-27 16:57:17 UTC 
OOM, related to latter bug #234463 claims?
In that case reproducibility is in the cards.

@pedron
does that also happen if quit plasma before copying?
("kquitapp plasma-desktop" - or just pkill it)

Hello!

Yes I'm quite sure, every time I'm trying to copy a large number of files, it seems after some time, something goes wrong and the whole desktop is disconnecting, or just lets me the windows open, but nothing else...
The complete UI doesn't slow, at least it seems.

>@pedron does that also happen if quit plasma before copying? ("kquitapp plasma-desktop" - >or just pkill it)

I will try this command, as it seems sometimes plasma ends itself.

Thank you both for your help, I'll keep posting evolutions here!

Hello,

It seems it works doing that. I'll reboot my computer after to re-load plasma desktop.

Thanks !
Comment 5 Thomas Lübking 2013-07-17 12:38:45 UTC 
It's not required to reboot or something, just running "plasma-desktop" (from krunner or konsole etc) will do.

*** This bug has been marked as a duplicate of bug 318131 ***
Comment 6 Thomas Lübking 2013-07-25 21:01:00 UTC 
Rather bug #311799, since bug #318131 is claimed to have no relation to the plasma indicator.
