This is what currently happening for me during one of the tests:
ubuntuone_nautilus_observed_file_unref file=0x112ad90
ubuntuone_nautilus_observed_file_unref
uri=davs://storage.lappyfamily.net/Stuff/test/DSC00806.JPG
ubuntuone_nautilus_observed_file_unref path=(null)
I believe uon->observed should contain not the path as the key but the
pointer to NautilusFileInfo structure. Later on dereferencing should be
handled by removing the NautilsFileInfo using the pointer. This will
prevent the leaks of the hash table entries which will happen in case we
simply discard the URIs that do not return local paths.
** Description changed:
- Binary package hint: ubuntuone-client
+ This crash happens when a user is copying/cutting and pasting the
+ files/folders between local and remote storage. The code that removes
+ references to NautilusFileInfo does not check whether the file is indeed
+ a local one. NautilusFileInfo can change its underlying path in case the
+ file is being cut (copied) and pasted to the remote storage.
- This looks similar to bug 645931, though it's hard to tell until it's
- retraced.
- It happened while I was copying a large file to an SMB share. After
- nautilus restarted, I restarted the copy operation, and it completed
- successfully.
