Comment 1 Dominik Tritscher 2008-07-27 23:55:15 UTC

Could you please tell us what revision or release you compiled?
Anyways, I can confirm that bug with KDE 4.1RC1 from Kubuntu packages.
My backtrace looks quite the same, so I don't post it here again.

Comment 2 SlashDevDsp 2008-07-28 03:04:17 UTC

The rev I am using is: 837925

Comment 3 Aaron J. Seigo 2008-07-28 19:39:36 UTC

SlashDevDsp: i can't reproduce this myself, but i did commit a fix in r#838767. can you test with that (or newer) kdelibs and let me know if that helps this issue? thanks...

Comment 4 SlashDevDsp 2008-07-29 14:17:29 UTC

Created attachment 26475 [details]
get hot new stuff with internet disabled crashed plasma

Comment 5 SlashDevDsp 2008-07-29 14:23:52 UTC

this is with todays svn compile (about 2hrs ago) with kdelibs at r#839063 and it still crashes see attachment in previous comment.

another thing to note: 
I have networkManager disabled (no networking). After getting the error dialog about not able to get new sources from GHNS plasma crashes.

Comment 6 Bill Rosmus 2008-10-09 03:49:58 UTC

I just had this same error using Fedora Core 9 K Desktop Environment Version 4.1.1 (KDE 4.1.1).  I have my wired internet connection (eth0) disabled but wireless (wlan0) running.  

Not sure where to find the stack trace for this... checked the systems logs and can't find anything relating to plasma.  Anyway, there it is... I just had the same error.  Tried several times... same error every time.

The reporter of bug 182593 experienced this using 4.2. Reopening

Comment 14 marco 2009-04-26 14:59:18 UTC

I have recently tested in Kubuntu 9.04 (Kde 4.2.2 & Qt 4.5.0) and still happens the same

1) Internet connection "disabled".
2) Desktop settings -> new wallpaper -> "there was an error loading data providers" message with OK 
3) Click OK and plasma dies.

Here its the backtrace:

Comment 15 Christoph Feck 2009-05-24 20:38:35 UTC

Can you reproduce the crash with KDE 4.3 beta1 ? Does the crash only occur with Plasmas wallpapers/themes, or does calling e.g. "khotnewstuff4 YOUR_KDE4PATH/share/config/icons.knsrc" also crash when no connection?

Thanks for testing.

I have recently re-tested this bug in Kde 4.3 Beta1 and also in Trunk20090519
and still crash. Here it the backtrace:

Comment 17 Christoph Feck 2009-05-25 20:03:22 UTC

SVN commit 972805 by cfeck:

Fix crash in Wallpapers GHNS when no providers are found

The problem was this: If you have an Internet connection, you
can download the list of provided themes, and GHNS caches that.

If you later open that dialog, but have no Internet connection,
then the dialog will show cached entries, but still say "No
providers found", and abort the dialog. After that abort, the
engine is deleted, but the dialog is not closed.

When we later get a paint() event, we crash because the model
for the items has already been deleted.

The fix changes the slot to close the dialog before returning
to the event loop in case the providers were not found, so that
the dialog has a chance to delete the widgets before the engine
is deleted.
