--- Comment #10 from Jim Jin <1830811...@qq.com> --- (In reply to Julian Morgan from comment #0) > Application: plasma-discover (5.12.5) > > Qt Version: 5.10.0 > Frameworks Version: 5.45.0 > Operating System: Linux 4.13.0-41-generic x86_64 > Distribution: KDE neon User Edition 5.12 > > -- Information about the crash: > - What I was doing when the application crashed: I have just installed KDE > neon (current user on 9/5/18) today on MacBook 3,1 from USB installer > created with Etcher, in the hope that it might give me faster boot times > compared to UbuntuMate. I have done very little from fresh install: Updated > using built in updater, moved bottom panel to top of screen and lastly > opened Discover to search for Latte as a "dock" alternative. After enter the > letters "latte" into the search bar I hit return and it crashed, tried again > and a third time same result. Hence this report. I hope it maybe useful > because I've done nothing since fresh install. Also might be relevant that I > am getting very slow start up times and on Mate this was due to > drm_kms_helper errors in that applying the worka round kernel boot parameter > video=SVIDEO-1:d into grub massively improved start up time. It seems to be > someting to do with the GMA945 (?) graphics on older macbooks removed from > more recent kernel versions, in that this error did not happen before 13.x I > only mention it because it is peculiar to this hardware > > - Unusual behavior I noticed: > Bottom left of desktop is a vertical text saying 'Default' > > The crash can be reproduced every time. > > -- Backtrace: > Application: Discover (plasma-discover), signal: Segmentation fault > Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". > [Current thread is 1 (Thread 0x7f680bc7b8c0 (LWP 2010))] > > Thread 7 (Thread 0x7f67c5cd0700 (LWP 2019)): > #0 0x00007fff71842b6d in clock_gettime () > #1 0x00007f6806faf876 in __GI___clock_gettime (clock_id=1, > tp=0x7f67c5ccfa70) at ../sysdeps/unix/clock_gettime.c:115 > #2 0x00007f6807bd0ed1 in ??
