I have an issue with the KDE panel that frequently freeze. Any part of it (the task manager, the clock, the system tray, etc.) cannot be interacted with; the rest of the system works fine as I can alt-tab between open apps, I can access the Run window with ALT+F2, etc. It started few* weeks ago with KDE 4.10.5 and the following upgrade to KDE 4.11.1. At first I thought of a corrupted config file, but last Saturday I did a totally clean Gentoo install installing directly KDE 4.11.1 using the following keywords: http://git.overlays.gentoo.org/gitweb/?p=proj/kde.git;a=blob_plain;f=Documentation/package.accept_keywords/kde-4.11.keywords and the problem persist The freeze happens independently of the open programs (for instance, during the night I don't have any program open beside those on the system tray and daemons on background). Beside that, the freeze is not even constant in term of time: some time it happens after hours and other times after minutes from the previous occurrence. When it freeze it does not generate any explicit error (except for the one I'll report in a moment) or the usual bug report window. The only workaround so far is to open Konsole (fortunately I keybinded it) and run: killall plasma-desktop && plasma-desktop that close and recreate the panel that become functional until the next freeze. On the Konsole it generate the following output: http://pastebin.com/Btk3ZkTC and then it repeat that "NETWM: Warning readIcon() needs buffer adjustment!" until it freeze and than it gives: *** glibc detected *** plasma-desktop: corrupted double-linked list: 0x00000000021fd850 *** Any idea on how can I fix it? If you need any other info or logs, just ask. Thanks. *at first I thought that the freeze was just a bad coincidence and than a bad mix of personal time constraint and general laziness made me endure it for days by keep using "killall plasma-desktop && plasma-desktop"; eventually now I cannot recall the exact day it started so I cannot correlate it with any specific upgrade of other software as possible cause of the problem.
I'm not sure what to suggest sorry. You could try reporting upstream.
I tried to open it upstream. For reference: https://bugs.kde.org/show_bug.cgi?id=324801 I'll let you know if I get any news from there.
Two comments in upstream bug report saying this problem is gone with 4.11.2.
Sorry if I didn't follow up on this bug; when I originally reported on upstream that the problem seemed to have been fixed (collaterally), I thought to leave a couple of days for further confirmation that the bug disappeared and in case the devs had any further questions on the case. After so many days I can confirm that after these updated on October 7th: kde-base/plasma-workspace-4.11.2-r1 kde-base/kdebase-runtime-meta-4.11.2-r1 kde-base/kdeplasma-addons-4.11.2-r1 the problem disappeared. Thank you. :)
Ops, I didn't finish correctly the first paragraph, I was saying "... I thought to leave a couple of days ... but then I got busy with issues in RL and I couldn't come back to close the bugs. :D
