ipython/ipython3 crash on qtconsole mode

[avlas]

Here it is the error I get in the console:

:~$ ipython qtconsole

I think it's a packaging problem in Raring with the dependency on PyQt, since PyQt 4.10 is installed. Actually, it was working before in Quantal and it also works if I install development version from ppa:jtaylor/ipython-dev

[Thomas Kluyver (takluyver)]

It's already fixed upstream, as you noticed: https://github.com/ipython/ipython/pull/2831

We're planning a 0.13.2 release soon that will include this fix.

Great, thanks!

[Julian Taylor (jtaylor)]

there wasn't much point in fixing it earlier as until yesterday pyqt itself was broken.
Now it will be fixed soon.

[Launchpad Janitor (janitor)]

This bug was fixed in the package ipython - 0.13.2~rc2-1

---------------
ipython (0.13.2~rc2-1) experimental; urgency=low

  * New upstream release candidate (LP: #1161818, #1162112)
  * pass -a to xvfb-run
  * drop DM-Upload-Allowed, not needed anymore
  * don't link documentation of ipython-doc so ipython3 does not depend on
    ipython (Closes: #695554)
    Requires ipython-doc.preinst to not lose copyright on upgrade
  * add ipython3 and ipython3-qtconsole desktop files (Closes: #693612)
  * fix detection of cython modules for multiarch python (Closes: #697704)
  * don't install tests for notebook and qtconsole
  * bump standard to 3.9.4, no changes required
  * add autopkgtests running testsuite and testing tools, cython magics
    and incomplete install message
  * fix crash on tracebacks without line numbers (Closes: #701597)
  * add tkinter package to debianize-error-messages.patch (Closes: #701707)
  * use canonical vcs fields in control
