Notification area crashed upon booting to the live DE (i386 only)

[Erick Brunzell]

Apport displayed this report at end of installation so I decided to let apport do it's collecting.

I see now this refers to mate-panel so possibly because the notification area had to be relaunched upon booting into the live DE?

This is a first-look for me when it comes to Ubuntu MATE so I have to learn the new package names, etc.

I suspect bug #1425499 may be a duplicate of this, or at least related.

[Launchpad Janitor (janitor)]

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

[Seth Johnson (sethj)]

I encountered this in the live session and after install and reported it here https://bugs.launchpad.net/ubuntu/+source/mate-panel/+bug/1425375. Apport made my bug private though, so I have marked it as a duplicate of this one.

[Erick Brunzell (lbsolost)]

I'm testing 20150225 i386 now and did not see this just booting to the live DE, I'll wait and see what happens at the end of installation.

@ Seth Johnson, I noticed that both of my MATE bug reports were private so I had to switch them to public so they could be read. Maybe the Ubuntu MATE devs need to change some Launchpad setting????

[Martin Wimpress (flexiondotorg)]

Also seen this, but only on i386. amd64 is fine.

[Martin Wimpress (flexiondotorg)]

PowerPC is also fine. Just i386 is affected.

[Stephen Cook (stevecook172001)]

Yep, I am using ubuntu mate 14.04. Notification area crashes on every login. Has to be reloaded. Usually fine for rest of session, but about 10% of time crashes again during session

[Stephen Cook (stevecook172001)]

should add, am using i386

[Martin Wimpress (flexiondotorg)]

@stevecook172001 Are you sure you mean 14.04? Please post the output of `lsb_release -a` on the affected computer.

If you are indeed running 14.04, can you tell me if you have the following PPA enabled?

  * https://launchpad.net/~ubuntu-mate-dev/+archive/ubuntu/crazy-mate

If you are running 14.04 and have that PPA enabled, then I believe this is a regression in GTK2 because I have built to next GTK2 release in the PPA above.

[Christopher (soft-kristal)]

I have 15.04 running on two partitions of two laptops; one an older i386 and the newer an AMD64. I experience the bug on the former upon every boot but not at all on the latter.

Neither have the PPA crazy-mate installed.

[Martin Wimpress (flexiondotorg)]

OK, this looks like a regression in GTK2.

I have installed Ubuntu MATE 14.04 on i386. All works fine. I then add the following PPA where I have backported GTK 2.24.26-0ubuntu1 from Vivid.

  * https://launchpad.net/~ubuntu-mate-dev/+archive/ubuntu/crazy-mate

I now experience the exact same crashes in 14.04 that I've experienced on 15.04.

[Martin Wimpress (flexiondotorg)]

gtk+2.0_2.24.26-0ubuntu2 has been released that fixes this issue.
