[I am a GCI student] In general unreproducible bugs are helpless. Do you remember anything special about your configuration at that time or what you had done in that session? We have a couple of crash reports with backtraces in KItemListView which might be related (bug 308348, bug 314019, bug 317970, bug 330966, bug 337204). It seems that there might be some sort of memory corruption going on in some cases, but unfortunately, the crashes occur only rarely and are not reproducible, so it was not possible to identify the root cause so far. [I am a GCI student] For all the listed bugs but bug 308348 there also seems to to be a connection with QHash. Bug 314019 and bug 317970 look specially related. Additional 'special' info: The folder that the file was being copied into was a git folder, with fileviewgitplugin active. It's not the first time that dolphin crashed (rarely but above average of KDE), but this time the action that led to it was obvious enough for me to report it, even if not being reproducible. *** Bug 377716 has been marked as a duplicate of this bug. *** *** Bug 378462 has been marked as a duplicate of this bug. *** Same here when dragging a file to a different tab to create a link. Application: Dolphin (dolphin), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

basic stress test
I've attached a demo stress test for this scenario. You can add a few variations for it, if you think it may trigger this segfault).
I also tried a number of extra things(that I taught might cause the error), but so far, I had no success.
Created attachment 118125 [details] Updated tab copy stress I misread the ticket initially thinking that the segfault was happening when switching tabs. This being considered, I've updated the test script to do some real copying between tabs. You can find attached the script for copying files between tabs and the video on how to do it (https://drive.google.com/open?id=1WTY6g1w2uxC05urH_rviiJ-DXOdEHm3U). Modifying the script to copy directories instead of files is trivial enough. That being said, I've retried this for quite a number of times (with files, directories with files, directories with files inside other directories), but I still haven't managed to reproduce it (not even once). Considering how old this ticket is, the issue might have been resolved inside the KF, Dolphin or Qt (I wouldn't bet money on this statement). Anyway, if anyone is successful, please let us know. can't reproduce even with the git plugin installed. Thank you for reporting this crash in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the crash with a recent software version? If you can reproduce the issue, please change the status to "CONFIRMED" when replying. Thank you! Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information. For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging If you have already provided the requested information, please mark the bug as REPORTED so that the KDE team knows that the bug is ready to be confirmed. Thank you for helping us make KDE software even better for everyone! |
