Bug ID: 374129
Summary: KDE Crash exactly one time per boot up session
Product: kwin
Version: 5.8.4
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: mwinth...@comcast.net
Target Milestone: ---
Application: kwin_x11 (5.8.4)
Qt Version: 5.6.1
Frameworks Version: 5.28.0
Operating System: Linux 4.4.0-57-lowlatency x86_64
Distribution: Ubuntu 16.04.1 LTS
-- Information about the crash:
- What I was doing when the application crashed:
On this occasion I was opening LibreOffice for the first time after
re-installing it. See below for repeatability with other applications.
- History of this error:
Prior to the gigantic update I installed 21 Dec 2016 this same error occured
except I could not install the debug tools. I tried to create a manual report
but never succeeded.
1) I upgraded from Kubuntu 14.04 to Kubuntu 16.04 over a year ago. The
process crashed during installation. I used a list of all the instllation
systems and completed all the missing items successfully. There were some
concerns that remain:
a) On startup Cadence would not auto start: "Bridge type:
ALSA->Loop->Jack" each time I started from boot up. It auto-started every
second time. This is still true and repeatable.
b) Window decorations would not show the title bar (hidden above the
left corner of the screen). Must use <ALT> <right mouse> to move window. This
is still true and repeatable.
c) Most applications start up w/o kde plasma crash when first window is
started, however, if that application opens a second window, the crash occurs.
This is still true and repeatable.
d) Once a crash has occured, further crashes generally do not occur.
This is true whether I restart KDE (Plasma) or not.
e) Icons on the desktop could not be <right click><start>. An error
about the format of the icon link is sees. The same icon could be <double
clicked> to open the application. No icon worked. This changed but not for the
best. (see below - same issue)
f) The partition reports itself as Ubuntu 14.04
2) I think I have two copies of KDE (Plasma) running at the same time and one
interferes with the other until on crashes.
3) I currently have some new problems, however I was now able to install kde
debug tools.:
a) On startup Cadence would not auto start: "Bridge type:
ALSA->Loop->Jack" each time I started from boot up. It auto-started every
second time. This is still true and repeatable.
b) Window decorations would not show the title bar (hidden above the
left corner of the screen). Must use <ALT> <right mouse> to move window. This
is still true and repeatable.
c) Most applications start up w/o kde plasma crash when first window is
started, however, if that application opens a second window, the crash occurs.
This is still true and repeatable.
d) Once a crash has occured, further crashes generally do not occur.
This is true whether I restart KDE (Plasma) or not.
e) Some Icons on the desktop can not open <right click><start>.
i) E.g., a desktop folder: An error about the file system being
unwritable occurs. The same icon could be <double clicked> to open the
application with the same error ("dolphin - KDialog... Configuration file
'/home/dad/.config/dolphinrc" not writable. Please contact your system
administrator') occurs. After acknowledging the error, the folder opens in
dolphin (both cases). Now some icons work. This change is still not for the
best.
ii) I had the same problem for LibreOffice and looked at the
file directory in question. It was marked drwxr--r-- O set it to drwxrwxrwx
but this still failed. I did a purge and deleted the directory. The re-install
fixed it.
iii) "-rw-r--r-- 1 root root 2055 Aug 3 17:16 dolphinrc" is
what I see. Since dolphin is run by the O/S, Once started, dolphin can start
other applications the read and write.
iv) <right click> on a folder and select <open> does nothing.
v) <right click> on a folder and select <open with> then select
<utilities> and then <files> and the plasma desktop changes to large icons,
reorganized. I did not select "use this every time" option. The file system
application that opens is "files", not dolphin. "file does not complain ("file
- KDialog... Configuration file '/home/dad/.config/filetyperc" not writable.
Please contact your system administrator') if I select dolphin, it complains
and then works. konqurer and Gwenview have no problems. Kid3-qt works but is
not a file system application. One wonders why writaility is needed. I used
chmod 646 dolphinrc and the error went away.
f) The partition reports itself as Ubuntu 14.04
