[Cristian Aravena Romero]

[Impact]

nautilus sometime segfaults when closing windows with several tabs open

[Test Case]

check https://errors.ubuntu.com/problem/a69a395811666090e103b1a48890e12ef0b433b5

or

try closing nautilus windows with several tabs open, that shouldn't lead to a segfault

check for issues on closing and with multiple tabs

Hello Cristian, or anyone else affected,

Accepted nautilus into trusty-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/nautilus/1:3.10.1-0ubuntu9.8 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

[Chris J Arges (arges)]

Does this also need to be fixed in Utopic?

[Sebastien Bacher (seb128)]

@Chris, we could, but utopic is going to be non-current-stable this month and is not a LTS, I don't fancy much spending SRU work on it now

[Mathew Hodson (mhodson)]

I don't see this crash when running the test case on 1:3.10.1-0ubuntu9.8 from trusty-proposed.

[Chris J Arges (arges)]
