Description Mika Tikka 2008-07-07 17:55:52 UTC
Version:            (using KDE 4.0.83)
Installed from:    Fedora RPMs
OS:                Linux

After changing some of KGet options, it crashes every time I start a download from Konqueror. Changed at least these: "use KGet as default d/l manager", "disable tray icon", "close after d/ls complete", "disable dropicon", or some options similar to those, forgot the exact wording. Here is the backtrace:

Please read the following page and provide a useful backtrace for this crash : http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

Also giving details about the settings that were changed or pasting the content of the kgetrc file would be useful.

Comment 4 Mika Tikka 2008-07-10 14:24:41 UTC
Tried removing ~/.kde/share/config/kgetrc. Now when downloading something, it asks for the directory, but download is saved as (for example if I download the top-left logo on this page) Documentskde_gear_64.png, not Documents/kde_gear_64.png. After it is completed, kget crashes.
Comment 5 Lukas Appelhans 2008-07-16 13:06:25 UTC
Well this seems like a crash in KIO itself...

Comment 6 David Faure 2008-07-16 13:19:13 UTC
Well, between this one and 166435, I'm wondering if kget isn't sending dead references to KUrls to KIO :)
Getting a valgrind log of this crash would be necessary.
Comment 7 Mika Tikka 2008-07-17 18:49:53 UTC
With KDE / kdenetwork updated to 4.0.85 crash no longer seems to occur.
Comment 8 Lukas Appelhans 2008-07-17 18:53:30 UTC
4.0.85 is kind of old, but I will close this ;)
