This seems related to bug 202880. - Which widgets related to system information do you have in your Desktop ? Thanks Detection the reason of crash may be problematic, cause I have 5 widgets related to that: - System Load Viewer - System Monitor - processor - System Monitor - temperature - System Monitor - network - System Monitor - RAM memory Mh, at least they are all supported widgets... (not like bug 202880); so the real bug may be somewhere else.... *** Bug 222076 has been marked as a duplicate of this bug. *** Bug 222076: Sysinfo widgets I am running: * System Load Viewer * System Monitor - CPU It might be worth looking at the extra information in my bug report. From bug 222692: -- What I was doing when the application crashed: When trying to mount an external drive from the device notifyer the desktop crashes. The device gets mountet and the dolphin window shows but the rest of the desktop is gone. The device is a mobile phone ( Samsung Galaxy running Android ) It's probably related to the name of the volume since it shows up as "/media/_PNG???" mount says: /dev/sdc on /media/_PNG ▒ type vfat (rw,nosuid,nodev,uhelper=hal,uid=1000,utf8,shortname=mixed,flush) Hex editor says:_PNG... is 5F 50 4E 47 0D 0A 1A Looks like there is a CR+LF in the Volume name????? mountig the volume manually from the command line to /media/phome works without crash. From bug 223316: -- What I was doing when the application crashed: KDE crashed after battery power runs out (<5%), the computer went in suspend mode automattically. After plugging in power again and some flickering, kde crashed. *** Bug 223316 has been marked as a duplicate of this bug. *** *** Bug 222692 has been marked as a duplicate of this bug. *** Ah, yes, ksysguardd would indeed screw up big time if the device name had \n in it :-/ Unfortunately, it seems many phone do this. For reference, mine is a Nokia E75 and it (sometimes...?) does the same. Alternatively, my Debian Lenny with KDE 3.5.10 is more resilent and/or parses those bad chars out. _If_ you decide to simply remove those bad chars, make sure you don't end up with an empty string, though. If you do, UUID or similar comes to mind ;) I think I fixed this - please could someone check in KDE4.4 RC2 or newer marking as needsinfo SVN commit 1077383 by johnflux: Fix off-by-one error in systemmonitor data engine. There is a check to see if we are in a consistent state. However the check is faulty, leading to engine trying to parse in an inconsistent state, leading to a segmentation fault. CCBUG:222692 CCBUG:206049 M +1 -1 systemmonitor.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1077383 SVN commit 1077388 by johnflux: Fix off-by-one error in systemmonitor data engine. There is a check to see if we are in a consistent state. However the check is faulty, leading to engine trying to parse in an inconsistent state, leading to a segmentation fault. CCBUG:222692 CCBUG:206049 M +1 -1 systemmonitor.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1077388 Two commits - first is in master (For KDE 4.5) and the second is in the 4.4 branch, but didn't make it in time for 4.4 RC2. - No more reports in KDE SC 4.4.0. Assumming it is fixed. |
