Description Jure Repinc 2015-08-11 16:38:30 UTC

I'm using beta version of KDE Plasma 5.4 desktop and Xorg server version 1.17.2. The graphics card is
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Park [Mobility Radeon HD 5430/5450/5470]

The problem happens when you are downloading something and the spining download indicator shows up in the tray. If you don't click on it to show the details all is fine. But if you click on it then after some time X server just restarts.

I connected to the computer via SSH and attached gdb to the server. And this is what happens:

Program received signal SIGPIPE, Broken pipe.

after continuing all was still working fine and the server didn't restart at this point. But it did after the following:

Comment 2 Jure Repinc 2015-08-16 11:33:38 UTC

Today I got this crash without progress details being shown. So it looks like the crash can happen in more cases and it is maybe just the easiest to trigger when the progress dialog is shown.
