Bug 180757

I have just tried other cities using the other weather services and am still experiencing the crash.
I should add, since it just occurred to me, that after the upgrade to RC1 I deleted my .kde to generate clean configs.
After logging in I noticed that the plasma applets where not being found.
I reinstalled plasma and the applets came back. 
[Related side note: shouldnt the default applets be stored outside of the users kde folder?]
Im thinking that if I am the only one experiencing this that it might be related although the other applets Ive tried seem to be working fine.

please visit this page:

http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

and collect a full backtrace so we can see where the crash is happening. thanks.

I have the same problem but have found a work around. When you search for the city, make sure that you double click on the name in the search list before closing the configure window, then it does not crash. 

There is no crash window  and .xsession-errors is empty, so I have no idea how to provide debug info for the plasmoid. The screen just blanks out after closing the configure screen, then the desktop comes back with the plasmoid and its configure button in its centre.

The weather source was the BBC and search was for "Milton Keynes". Packages are Kubuntu KDE4.2 rc1

I suspect Scott's crash is due to the Qt crash.
Scott please can you retry by NOT using the Configure button but using the Settings icon in the applet handle. Does it still crash? If so please provide a full backtrace as Aaron pointed in Comment #2.

Georges can you also try it. If your crash persists you should also get us a backtrace because without it it's difficult to say anything. Try installing the debug packages for your distribution.

Thanks in advance for following it up.

Anne-Marie,

Yes if you ignore the configure box and use the settings icon then the applet does not crash when the settings dialog box is closed.

I also ran it from the plasmoidviewer and got the following output while using the configure button route. 

$ plasmoidviewer weatherstation
plasmoidviewer(26123) WeatherConfig::validate: *** DANGLING SOURCES BEFORE *** ("bbcukmet|validate|Milton keynes", "ions")
plasmoidviewer(26123) WeatherConfig::validate: *** DANGLING SOURCES BEFORE *** ("bbcukmet|validate|Milton keynes", "ions")
Object::disconnect: No such slot QObject::dataUpdated(QString,Plasma::DataEngine::Data)
Object::disconnect:  (sender name:   'bbcukmet|validate|Milton keynes')
Object::disconnect:  (receiver name: 'weatherConfig')
$

I have the same crash with my system. Unfortunately Kubuntu does not seem to provide dbg-packages for all of the KDE4.2RC1, so can not help a backtrace.

Ok, I managed to get a backtrace but it claims to be of no use though it appears I do have some debugging symbols installed but I'm not sure how to tell since the kubuntu RC1 packages to not have a seperate -dbg package included.
Using plasmoidviewer weatherstation, I did not experience the crash.
Heres the backtrace I managed to get:

This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.

Hopefully thats useful.

I get the same. Unfortunately there is no debug-package for Kubuntu or I could not find it.

Scott, m.wege: can you reproduce the crash when you use the small Settings icon on the applet handle instead of the Configure button?

Scott your backtrace points to the upstream Qt bug which is fixed in qt-copy with a patch and happens only when using the Configure button, not when using the Settings icon on the applet handle. If so, I'll close as UPSTREAM.

I have tried and can confirm the crash does not appear when using the small settings Icon is used. 

Thanks to all.
This crash which happens when using the Configure button and not when using the Settings icon on the applet handle is fixed in qt-copy and is from a Qt bug.

Fixed in next Qt release.

I have the same problem here both in latest svn and 4.2.0 kubuntu packages.
It doesn't crash if I use the handle.
