Description Sebastien Bacher 2008-03-26 17:43:01 UTC 
The bug has been opened on https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/206539

"Was copying a file called ".purple.rar" from a FTP hosted on a system running Vista SP1 x64 with FileZilla FTP Server v0.9.25 beta. On the same note, Nautilus would simply refuse to copy a directory named ".purple" or any of its contents from the same FTP server.

Partial fix to the problem

This patch partially fixes the problem by catching NULL jobs in gvfsjobread.c, but the larger problem is where the NULL job came from to start with.

Is this bug reproducible and if so does it happen also with later (1.x) versions of gvfs? (Atleast one nasty memory-corrupting crasher has been fixed in the gvfs ftp backend since 0.2.x.)

Can anyone provide access to "a system running Vista SP1 x64 with FileZilla FTP Server v0.9.25 beta", or know of a public host running this ftp server software, for testing?

I think the segfault only shows a symptom of the problem which occurs erlier.
I'd be interested in looking into the problem if more information is provided!
