[Bug 93675] Nautilus crashes on recursive symlinks

[Manuel Freire]

Public bug reported:

Binary package hint: nautilus


Testcase:

cd /tmp
ln -s foo foo
# foo is now a symlink to itself, and the following crashes:
nautilus /tmp

More complex testcases also fail:

cd /tmp
rm foo
ln -s foo bar
ln -s bar foo
# foo points to bar points to foo ... and
nautilus /tmp  

crashes again

Possible fix:

While expanding symlinks, check to see if any "next" hop is already
present in the current or previous hops. If found, abort the expansion,
and mark the original symlink invalid (= detect loops).

Impact:

This is unlikely to happen to anybody with better memory than mine on
the quirks of "ln -s". However, it seems easy to solve...
