Crash when backing up to SFTP

[Michael Terry]

From user Jonathon Hodges:

"I have a Déjà Dup backup at a remote location which I have a login to using SSH. I'm trying to backup to that over the internet. Déjà Dup will happily open the SSH (SFTP) folder in Nautilus through the preferences but when I hit Backup, it crashes straight out.

The last part of the strace log is:
15:45:19.050680 brk(0x8d43000) = 0x8d43000
15:45:19.050758 brk(0x8d42000) = 0x8d42000
15:45:19.062240 brk(0x8d63000) = 0x8d63000
15:45:19.080000 brk(0x8d84000) = 0x8d84000
15:45:19.080081 brk(0x8d83000) = 0x8d83000
15:45:19.089591 --- SIGSEGV (Segmentation fault) @ 0 (0) ---
15:45:19.098837 +++ killed by SIGSEGV +++

I'd be grateful if you have any suggestions what's wrong?"

Jonathan, are you using Ubuntu? If so, could you install the deja-dup-dbg package and create a backtrace [1]? If not, do you know how to build deja-dup with debug symbols and create the backtrace?

Hi Michael,
I am using Ubuntu (Karmic Netbook Remix). Here's the backtrace, please let me know if there's anything else I can do to help out or if I've not followed the instructions correctly.

Kind regards,
Jonathon

Sorry for the late response. This looks like a bug in the vala compiler. I'm trying to create a small test case and will submit it upstream.

[Michael Terry (mterry)]

Oh, and by the way, thanks so much for providing the traceback. :) I wouldn't have figured this out without it.

[Jonathon Hodges (jonblondie)]

No problem Michael, I'm not able to contribute any code so it's the least I can do to help out.
