[apport] gnome-panel crashed with SIGSEGV in _int_malloc()

[C de-Avillez]

Binary package hint: gnome-panel

This one *may* be related to the many others we currently have opened -- bug #81520 jumps out, plus the others, including bug # 81723, which we closed because I could not replicate it. The list is rather large, currently.

Now here's a bit of new info: I *do* remember, from 81723, that I was running a dist-upgrade at the time. On this one I was *also* running a dist-upgrade (and this is why I think 81520 may be quite related). I think one good chance is a race on updates on the panel, and usage. This is, I think, a race, because I have been updating quite frequently this install, and I only got hit twice.

Ah well. Let's see what can be seen.

libgtk20.0 2.10.9-0ubuntu2 is installed.

Thanks for your bug report. The crash looks like a memory corruption. Could you try to get a valgrind log for it? (you can follow the instructions from https://wiki.ubuntu.com/Valgrind for that)

[C de-Avillez (hggdh2)]

tried first run, but no success in reproducing the crash. I will wait to retry when we have a lot of updates to applications that affect gnome-panel.

Valgrind reports some accesses tha overlay freed blocks, but nothing fantastic.
