stef, there must be something spectial in that folder that makes nautilus crash.

Can you narrow it down?

Christian, any reason you set that back as NEEDINFO back? It has a debug backtrace

Christian Kirbach





          2006-09-26 17:30:55 UTC
        



yap I asked if the reporter can track it down to the item causing the crash.

hmm on the other hand we have a couple of duplicates and valueable traces so I am confirming this report now.

Maybe nautilus_file_get_uri returns NULL. Possibly, file->details->directory->details->uri is NULL. It would be very helpful to get a list of affected GnomeVFS modules. On the other hand, nautilus_directory_new asserts that precisely this variable may not be NULL.

Hmm, short of the NULL pointer parameter (directory vs changed_files) in the nautilus_directory_emit_change_signals() call, this looks like the very same issue as bug 343488.

Also, bug 350975 comment 56 got an identical stacktrace as bug 343488. Although that one differs from the original and the duplicates (without debugging symbols).


Could a Nautilus developer please have a close look at these? Are they actually the same issue? Note that bug 350975 is a blocker.

Yay, turns out my assumtions in comment 16 where dead right. :)

Alexander, I also just spotted a trail of evidence. The reporter of bug 361537 (which is a duplicate of this one) managed to reproduce and gather a stacktrace with debugging symbols, filed as bug 362581 -- marked instantly as a duplicate of bug 350452, which is a duplicate of bug 343488.  *phew*

Thus, this bug indeed is the same issue as bug 343488. Doesn't only look like a dupe. ;)

If anybody of the reporters do not use pre-compiled packages (provided by their distributor), but compile from the source code, please help us by applying the patch at http://bugzilla.gnome.org/show_bug.cgi?id=343488#c25 in order to test if this fixes this crash. Feedback highly welcome and appreciated (please add any comments to bug 343488), thanks everybody in advance!
