Status changed to 'Confirmed' because the bug affects multiple users.

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

When I select Edit -> Preferences -> Plugins - Python Console and then choose preference option on this plugin gedit crashes causing this error.

[Sebastien Bacher (seb128)]

is that still an issue?

[Dan Halbert (dhalbert)]

My oneiric is completely updated as of today, and I can still generate this crash (same scenario as comment #7). The python stacktrace is:

$ gedit
Traceback (most recent call last):
  File "/usr/lib/gedit/plugins/pythonconsole/__init__.py", line 65, in do_create_configure_widget

I have a patch for this that I submitted upstream. Will package it up after I decide if bug 857707 needs anything on the gedit side or not.

[Michael Terry (mterry)]

I've pushed a patch to oneiric-proposed (gedit 3.2.1-0ubuntu2) for this. This bug is a crash regression from 11.04.

To reproduce:
 * Select Edit -> Preferences -> Plugins -> Python Console
 * Enable it
 * Then click its "Preferences" button

gedit will crash, but it shouldn't with this patch.

Hello Joshua, or anyone else affected,

Accepted gedit into oneiric-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Jean-Baptiste Lallement (jibel)]

SRU verification for Oneiric:
I have reproduced the problem with gedit 3.2.1-0ubuntu1 in oneiric-updates and have verified that the version of gedit 3.2.1-0ubuntu2 in -proposed fixes the issue.

Marking as verification-done

[Launchpad Janitor (janitor)]

This bug was fixed in the package gedit - 3.2.1-0ubuntu2

---------------
gedit (3.2.1-0ubuntu2) oneiric-proposed; urgency=low

  * debian/patches/07_pyconsole_crash.patch:
    - Don't crash when opening the pythonconsole plugin's preferences
