"Binary package hint: gvfs

Nautilus file manager crashes EVERYTIME I try to access an ssh server through it.

* Open nautilus.
* In the address bar, type ssh://<address of your server>
* After you are connected, try to move some files between the two systems (your local and the ssh server)
* Nautilus will crash within a few moments
* Automatic crash-report generator starts up and collects whatever data it does collect.

Patch

I can reproduce this crash by cancelling a read/write operation from the nautilus progress dialog. The problem is that, in gvfschannel, new read/write requests are processed after a cancel request, so that new read/jobs are created that try to read/write on an already cancelled stream. This patch fixes the crash.

Hmm. I think this patch was actually wrong and is causing bug 535814. A stream is not cancelled, just an operation on the stream. With this patch we ignore the close operation after a cancelled read operation.

I reverted the patch in trunk.
I'm trying to reproduce the original crash, but is unable so far.

Close as obsolete, because I don't see any similar abrt crashes on https://retrace.fedoraproject.org/faf2 . Feel free to reopen if you are still facing this issue.
