Nautilus Segfault - Fedora 16

I encounter routine segfaults while navigating directories, specifically using the tree view. When nautilus segfaults, the entire file browser window disappears.

During heavy usage (e.g., writing code; several directory branches deep), I will typically see 2-3 segfaults in a single day. Lesser branching tends to reduce the frequency, but it still happens occasionally.

How do I fix? Do I need to report this to any organization (redhat, fedora, gnome?)... if so, how?

It's bugs like these that cause me to think twice about recommending fedora to anyone... if they can't get the basics right, what reason do I have to trust it with anything more complex.

Any help or suggestions (besides the obvious of avoiding tree view) would be much appreciated.

Also, using "LD_PRELOAD=/usr/lib/libGL.so.1 nautilus" as per http://forums.fedoraforum.org/showthread.php?t=273444 did not fix the issue.

Re: Nautilus Segfault - Fedora 16

Have you tried running it from the command line? It may display a useful message before it crashes. Also, have you checked the log files?

Re: Nautilus Segfault - Fedora 16

I have run it from the command line, but there was no revealing error message (besides SIGSEGV or whatever).

Which log files should I check?

Re: Nautilus Segfault - Fedora 16

There's a line about a segfault at some address (mentioning libglib-2.0.so.0.3000.2) appended to /var/log/messages.

There are also a bunch of errors printed to ~/.xession_errors. Since there are no timestamps in that log file, I don't know many occurred before/during/after the segfault event. Anyway, the errors are approximately "Got a request to focus the no_focus_window with a timestamp of 0. This shouldn't happen!" and "CRITICAL **: gedit_spell_checker_language_to_key: assertion `lang != NULL` failed." Both are printed numerous times.

Re: Nautilus Segfault - Fedora 16

I did not previously read those bug reports.

The first might be plausible. I am using akmod-nvidia. The only doubt I have is that my segfault mentions libglib which shouldn't have anything to do with any graphics subsystem.

The second link has a lot of users complaining of spontaneous behavior. What I see is not spontaneous. With several directories open, there's a small probability that when I try to open a file by clicking on it, nautilus segfaults. It only segfaults precisely when I double click a file.

I can't make sense of the third link. My system is reasonably up to date (updated last it had network connectivity, maybe 5 days ago).

I can look though the nautilus bug tracker to see if anything catches my eye. In any case, is there a good way to capture a stack trace or more information about the segfault. Nautilus through valgrind is pretty much unusable. I can reasonably expect when it will crash, but don't have a deterministic way to reproduce the issue.
