Crash when trying to add a Gadget in KDE4.2.2 #300

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Log in to KDE 4.2.2
2. Open the "Add Widgets" dialogue
3. Click in "Install New Widgets / Download New Google Gadgets

What is the expected output? What do you see instead?

I expect to see the Google Gadgets downloader / installer. Instead, I see a
crash! :)

What version of the product are you using? On what operating system?

Version 0.10.5-0.1+b1 on KDE 4.2.2 on a Debian SID system.

Please provide any additional information below.

The bug was originally reported against KDE's bug tracker:
https://bugs.kde.org/show_bug.cgi?id=191611

The KDE dev who looked at it instructed me to post the crash upstream.

This is the backtrace of the crash:

Hi,

Thanks for reporting this bug. 

Backtrace of thread 0 is missing.Could you run plasma within gdb to see if 
complete
backtrace could be got? 

When running plasma within gdb, parameter of "--nofork" should be used to avoid
plasma fork itself.

Hi

Follows the backtrace from gdb. Please reply if other info is needed.

Also, I have installed libglib2.0-0-dbg, which is the .deb package that holds 
the
debugging symbols for libglib-2.0.so.0, but the ??s at the end persisted.

This information is sufficient. It's a very serious bug. Thanks for reporting 
this.

This crash is caused by delete QHttp directly in qt_xml_http_request. Should use

Already fixed.
