Description Didier Raboud 2010-06-14 05:41:01 EEST

Hi, 

as I already told on IRC, the qtgui_wdiget test segfaults in PySide 0.3.2 (on
amd64).

I'm filing this here to get a constant reference for that problem.

Cheers, 

OdyX

The following code leads to a Segementation fault when invoking the layout()
method of the QMainWindow instance:

from PySide import QtGui, QtCore
import sys
app = QtGui.QApplication(sys.argv)
window = QtGui.QMainWindow()
window.layout()

-> Segmentation fault

Hardware on which issue could be reproduced: Intel 32-Bit running Ubuntu Linux
9.10 + Nokia N900 (PR1.2)

Comment 2 Hugo Parente Lima 2010-06-18 15:40:38 EEST

Works for me with git HEAD and a debug build.

[hugo@thinkpadugo tmp  4.6] $ cat > test.py
from PySide import QtGui, QtCore
import sys
app = QtGui.QApplication(sys.argv)
window = QtGui.QMainWindow()
window.layout()
[hugo@thinkpadugo tmp  4.6] $ python test.py 
[static Shiboken::TypeResolver* Shiboken::TypeResolver::get(const char*)] Can't
find type resolver for 17QMainWindowLayout
[hugo@thinkpadugo tmp  4.6] $ 

The warning about TypeResolver is expected and only show on debug builds.

Comment 3 Hugo Parente Lima 2010-06-18 15:42:13 EEST

Oops. my machine is running linux 64bits, so the previous tests doesn't apply
for this bug.

Unit test created in commit:

commit 28d0c480b15d566cabfb63dc6cc65697dc5b5edc
Author: Renato Filho <renato.filho@openbossa.org>
Date:   Tue Jul 13 17:53:59 2010 -0300


This prove the test is working on PySide HEAD.
the qtgui_wdiget was fixed too.

Comment 5 Kalev Lember 2010-08-11 14:42:40 EEST

I'm getting a segmentation fault running the newly-added unit test
QtGui_bug_243 with pyside 0.4.0 on Fedora 13 i686; not able to reproduce it on
Fedora 13 x86_64. All other unit tests (well, except one more which triggers
assertion in pulseaudio) run fine.

QtGui_bug_243 test appears to segfault on i386 debian unstable too:
https://buildd.debian.org/fetch.cgi?pkg=pyside;ver=0.4.0-1;arch=i386;stamp=1282585155
