crash when closing a file

[Robert]

Every once in a while Inkscape crashes when I close a (saved) document. (I press Ctrl+S and Ctrl+W, in case that matters.)

This is not tied to a specific file, and it doesn't happen all the time.

I usually can work and save files a few times before Inkscape crashes.

Let me know if / how I can provide more information.

Looks like https://bugs.launchpad.net/inkscape/+bug/967416

Can you confirm ?

[Robert (robert-wenner)]

I am not sure. How do I tell? Stack traces look different to me, but I don't know enough about these internals tos ay if they are really different.

I tried waiting between saving and closing, but the crash did not happen again yet. I'll keep trying.

[Robert (robert-wenner)]

Ok, I think it does happen on closing, not on saving. I just had a situation where I saved, then Alt+Tab'd to another app for a few seconds, came back to Inkscape and pressed Ctrl+W to close the file and it crashed.
