Hi, They're not similar enough that we can use that example as the basis of a bug report. If you have some sample code that reproduces the crash you're seeing on Maemo I'd love to take a look. If you don't have some sample code or quite a bit more detail about the crash I can't really do much.

But I think they have similar parts?? And they both have problems after closing UI.

Do you have any examples of the crash that use the Qt Mobility Location API?

Gps works nicely now. When testing sample Qt_for_Maemo_Location_Example, this seemed to have left something hanging after UI was gone, at least with debugger. All parts was not stopped and deleted. Hope this helps? The crash below happens after all UI has gone away and my app says "All cleaned!" in qDebug .Sounds very similar.

A test case based on the previous code that crashed all the time would be even more useful - if calling stopUpdates() more than startUpdates() is causing crashes that's a very serious bug that we'd like to solve as soon as possible. Both would be best, but I'd be grateful for whatever you can put together that doesn't take up too much of your time. That would make both confirming and fixing the bug much easier.

If that's not the case, which version of Qt Mobility is the program using? If you're not using the Qt Mobility from the git repository could you try that ( <http://qt.gitorious.org/qt-mobility/qt-mobility> http://qt.gitorious.org/qt-mobility/qt-mobility, master branch<http://qt.gitorious.org/qt-mobility/qt-mobility>). If it still crashes after that let me know. I'll file a bug based on the information you provide and make sure we get someone working on it as quickly as we can.
