Description Ralph Janke 2008-03-29 11:57:37 UTC
Version:           4.0.2 (using KDE 4.0.2)
Installed from:    Ubuntu Packages
OS:                Linux

Forwarded report from Kubuntu (https://bugs.launchpad.net/ubuntu/+source/kdebase-kde4/+bug/198794)

I was trying to use konqueror to look up the fonts database , so I did
fonts:// as the URL
it gave me an error saying either personal or System needs to be defined.
So I did fonts://System/
still it didn't come up.
Then I did fonts://System/System & it promptly crashed.
I get the Konqueror crash dialog box which says :-
The application Konqueror crashed the signal 6 (SIGABRT)
This is the backtrace in the next tab in the dialog box.

I can confirm this crash with kdelibs r790019. It seems to be a KIO problem and also occurs in dolphin.

The backtrace (for the dolphin crash) is:

Application: Dolphin (dolphin), signal SIGABRT

Comment 7 David Faure 2008-09-23 23:47:54 UTC
Even though the backtraces are the same (kdirmodel is the one showing the error), there should really be one bug report per kioslave, they need to be fixed separately. Too much merging isn't a good idea on this issue.
Comment 8 Frank Reininghaus 2008-09-29 23:54:04 UTC
David, the error message you added before the assert is (hope it helps):

dolphin(27112)/kio (KDirModel): First item has URL KUrl("fonts:/System/ae_Khalid.ttf") -> parent directory would be KUrl("fonts:/System") but that directory isn't in KDirModel! Root directory: KUrl("fonts://system/System")

I'm removing the people who were added to CC because we marked wrong duplicates.

Comment 9 David Faure 2008-10-01 11:55:37 UTC
The problem was that fonts://foo/bar means "hostname foo, path /bar", and
obviously kio_fonts doesn't care for a hostname (so it would list files without
the hostname, and KDirModel would get confused). I fixed this for all "local"
kioslaves in KDirLister by stripping off the hostname.
trunk r866552, 4.1-branch r866553.

I think I went through all the "duplicates" and fixed them too, but ping me if
I missed one.
