[apport] nautilus crashed with SIGSEGV in _int_malloc() (broken symlink)

[Sitsofe Wheeler]

Binary package hint: nautilus

Description of the problem:
After going to Places -> Home Folder then Places -> Desktop, nautilus repeatedly started segfaulting.

Steps to reproduce:
1. Log in to GNOME.
2. Set nautilus to the spatial view?
3. Go to Places -> Home Folder.
4. Go to Places -> Desktop.

Expected result:
Two nautilus windows to be open - one showing my home folder, the second the contents of the desktop folder in my home folder.

Actual results:
Nautilus crashes and an apport crash reporting window appears. Subsequent nautilus windows continue to crash.

How reproducible is the problem?
Currently unknown (haven't tried other than letting nautilus respawn itself). This is the first time this has happened since I started using Feisty.

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)?

OK found the problem. If you make nautilus browse to a directory with a broken symlink then you get this segfault. I'm sure I saw this reported elsewhere...

Looks like Bug #90934

[Sebastien Bacher (seb128)]

right, look like a duplicate, feel free to reopen if you still get the bug with the next version
