Comment 1 Dario Andres 2009-01-09 19:58:52 UTC

Can you still reproduce this bug? Thanks :)

Comment 2 Alex 2009-01-11 09:36:37 UTC

It's still the same problem in KDE 4.2b2 (4.1.85), Dolphin 1.1.80

Comment 3 David Faure 2009-01-13 23:45:25 UTC

I don't have access to a webdavs site to test this, unfortunately.
Do you have the debug output from dolphin (e.g. from ~/.xsession-errors)?

The following appears in .xsession-errors on crashing:

kdeinit4: preparing to launch 
ASSERT: "!name.isEmpty()" in file /build/buildd/kde4libs-4.1.85/kio/kio/kdirlister.cpp, line 1507
QObject: Do not delete object, 'unnamed', during its event handler!
KCrash: Application 'dolphin' crashing...
kdeinit4: preparing to launch /usr/lib/kde4/libexec/drkonqi

I noticed the same with Konqueror also, so its likely a general KIO problem.

Comment 5 Alex 2009-01-14 06:29:04 UTC

Oops, it looks like the same problem with plain (insecured) webdav also:

Comment 6 David Faure 2009-01-16 14:43:40 UTC

OK, clear enough, empty UDS_NAME.

Which URL are you opening? [does it contain a filename, or does it end with a '/']

Comment 7 David Faure 2009-01-16 14:51:03 UTC

Created attachment 30320 [details]
does this untested patch for kdelibs/kioslave/http/http.cpp help?

No filename, just "webdavs://hostname:2078/". If the trailing slash is omitted, Dolphin adds it automatically.

When I add a name of existing subdirectory, I can see a list of files flashed for a moment before Dolphin crashes again.

Sorry, cannot test it as I use binary Kubuntu packages.

Fixed after upgrading to KDE 4.2.2

Many thanks!

@David: should this be marked as fixed now ? Thanks

Seems so.
