Description Sean Chu 2015-05-24 21:29:40 UTC

I am using kde 4.14.6, and installed applications 15.04
every time i open a new tab, dolphin froze for 1 or 2 secs
same if I use 'save as' in other apps, the pop-up window to let you choose the location will also wait 2 secs to become active.
deleted ~/.kde4, better for a while, now still the same problem

Reproducible: Always

Comment 1 Frank Reininghaus 2015-05-26 17:06:11 UTC

Thanks for the bug report! In order to find out where in which part of the code it freezes (it's most likely not in Dolphin itself if you can also reproduce this with the file dialog in other applications), we need a backtrace. Please see https://community.kde.org/Dolphin/FAQ/Freeze for details. Thanks for your help.

Comment 4 Frank Reininghaus 2015-05-28 17:37:02 UTC

Thanks. The first backtrace shows no sign of a freeze or anything keeping the CPU busy for a long time. The second backtrace has QUrl::userName() on top, but I'm not sure if that is really the right function, or it was just a coincidence that the execution was interrupted there.

Please install debugging symbols, such that the backtrace gets more details: https://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

Moreover, it might help if you repeat the process several times and attach a couple of backtraces here. If some of them show the same function on top, then we might have found the culprit.

Thanks!

Comment 8 Frank Reininghaus 2015-05-28 20:19:49 UTC

Thanks. The backtraces are still not quite detailed because debugging symbols are missing, but it seems that most of them have frames in code that is related to the "Places" in the Places Panel.

There were some problems with the "Places" which should be fixed in kdelibs 4.14.8 and kde-baseapps 15.04.1. Can you upgrade to these versions and try if that helps?

Created attachment 92896 [details]

opensuse has not provided the newest version you mentioned, is there any
other way i can test it? i instored dolphindebug-info last time, was that
the correct way to provide symbol info?

For Dolphin itself, yes, but since the place where the CPU is busy is in kdelibs and Qt code, debug info packages for these are more important here. I thought that most distros install them automatically if you install the debug package for an application that depends on them, but it seems that I'm wrong.

But even if we get more detailed backtraces, I'm not sure if we could tell with certainty that the bug that you see is related to the fixed issues or not. An upgrade to a newer version would be the best test, but I see that this is not easily possible if the distro hasn't provided updated packages yet.

Comment 11 Julian Steinmann 2018-04-12 19:08:22 UTC

@Sean Chu, can you confirm that newer versions of Dolphin fixed this issue? If yes, I'll close this bug report soon.

Comment 12 Julian Steinmann 2018-04-28 17:04:22 UTC

Probably fixed & no response -> closing. Please reopen the report if you can still reproduce this issue with newer versions of Dolphin. Thanks!
