There seems to be a problem, in that when moving the cursor outside of a qtconsole window while there is an active pop-up hint, IPython will segfault.
type a command and end at an open parenthesis, e.g:
move the mouse cursor out of the qtconsole window area
The ipython session quits, and "Segmentation fault" is printed to the terminal.
What should happen:
Nothing, presumably. Perhaps the tool-tip should go away.
Anyone else seeing this?
Ubuntu 11.10 x64
iPython 0.12 trunk (7e0d999, October 21, 2011)
python-qt-dev 3.18.1~4ubuntu3 (from repos)
python-zmq 2.1.9-1 (from repos)
N.B. python-qt-dev is related to Qt 3, whereas we're using Qt 4. It may be important whether it's using PyQt (python-qt4) or PySide (python-pyside).
I've now tested with both, by doing
export QT_API=pyqt and export QT_API=pyside
It only crashes with pyside, and works as expected with pyqt.
OK - I think this has come up before, and we've concluded it's a bug in PySide, and there's not much we can do about it. So I'm going to close this issue. Thanks for reporting it, and I hope it gets fixed soon.
